My solution to the lack of aux jack on the car dock.

I agree that having an aux jack on the Nexus One car dock would be pretty sweet, but it is what it is, and I wanted to move on... Here is what I did:
Nexus One (duh)
Nexus One car dock (...)
Kensington LiquidAuxbluetooth car kit: us.kensington.com/html/14484.html
Micro USB cable
Plug the Kensington L.A. into the accessory outlet, and connect the audio output plug to your AUX on your stereo. The L.A. provides a USB port to use for the Micro USB cable. (for charging)
Plug the micro USB cable in this port and route to your car dock.
Once you pair your phone with the L.A. place it in the car dock and setup the audio to be whatever combination you would like. I personally use the dock for calls (because the mic is better) and the L.A. for audio.
One accessory outlet, (no splitters) one wire coming from it to the dock, audio routed through the AUX in your stereo, and (IMO) really great call audio thanks to the dock and noise canceling, which still works with the phone in the dock...
Just sharing my experience, YMMV, IANAL, OMG, WTF, BBQ...

+ 1. That looks like a really good solution. Another benefit you did not mention is that by powering the Car Dock with the Micro USB cable, you do away with the spiral lead that is on the Car Dock power supply. So easier to route and hide.
Any issues with charging the phone and powering the car dock? Isn't the car doc charger higher output than regular chargers and perhaps the one on the LiquidAux?

how's the music sound quality?

No issues I have noticed so far, there is no additional <warmth> on the LiquidAux I have been able to detect, and the phone charges just as quickly as it would when plugged in using OEM adapter. And yes, losing the spiral lead is a nice bonus...

Sound quality for me is great, there is no interruptions, etc I have noticed. But I suspect that this would be a YMMV kind of thing based on the car stereo used and the distance / path (if that even matters with the relatively short distance) between the LiquidAux device and the phone...

Why yes, but some people in this particular forum were voicing their displeasure of having a mass of wires dangling all over their car / phone etc...
I was offering an alternative, and it worked well for me, nobody said or implied that you need to do it too...

Hmm. I guess, worst case scenario, I can just buy a short extender.

Another question for you... Does the remote work with the phone? I'm waiting for mine to get here but I had read from many reviews that the control did not work properly with the iphone, just wondering if the nexus one had the same problem.
Sent from my Nexus One using the XDA mobile application powered by Tapatalk

awesome writeup... Even if this thing doesn't work to pickup calls I don't care, I always have a bluetooth headset for the car anyhow. I think I'll get an extra socket and mount it all under the dash out of sight.
Even thought you can plug in a wire to the headphone jack I want a solution where I can stick the phone in the holder when I get in, and pull it right out without messing with cables every fricken time... Most the time I don't plug my phone in right now just because of that very reason.
With a nice setup like this I'd plug my phone in every time I get in the car... awesome, Thanks!
Just ordered mine off amazon.. seems like a great price for the product.

Nevermind, reread your first post, missed the info I wanted the first read through. Well, since I'm stuck with this post existing, may as well clarify, you said you can choose to have the phone calls go through the dock with this, right?

The media functions work fantastic with the Nexus, the iPhone does not support track skip, where the Nexus does. I have not been able to get the phone button to start voice dialing like the iPhone does. I have not actually had a call while driving to pickup yet, so I can't say for certain whether that (pickup incoming) works or not...

I have call audio go through the dock, yes. The LiquidAux has a microphone, but it is quite far away from the the speaker's mouth IMO. Additionally, the dock still uses the extra Michael for active noise cancelling and is quite crisp and clear for calls. (I have so far made several outbound calls with great results.) The music pauses, audio routes up to the dock for the duration of the call, then the music resumed on the car speakers automatically...

[Q] MicroUSB Headset/Charger?

Has anyone seen a microUSB dock/charger/headset that has audio capability as well as charging the phone? What I'd like is to play music from, have headset controls from, and charge the phone all from the microUSB port on the bottom... or is this what car docks are supposed to do?
The way my car is, it's annoying to plug in the charger on the bottom AND the line out on the top - if there's a headset/adapter type thing, I figure I'll buy one of those and build my own car dock, and potentially speaker dock for the indoors.
OR: Just a microUSB headset - maybe I could add charger wires to it...

Month-long bump: I've realized that all I want right now is a microUSB headset, like for the older phones with no headphone jack. Obviously they don't make these for the G2x; has anyone confirmed another LG headset that works with this phone?

I honestly dont know if anything like that exists but I dont think so because of several reasons. Just a few that come to mind I'm not sure if the kernel driver supports it even if it could; the power running parallel to the audio probably would sound terrible; the USB would probably have to be used with a USB (female) to micro-USB (male) adapter since if you were to find it, it would probably be for PC so needed to be converted further adding to the reduction in sound quality.
Silly question.... why not just use Bluetooth and then usb to charge/data only??

Not a silly question at all. I don't feel like paying for a bluetooth adapter but also, because I've had bad luck with them in the past, as far as sound quality goes; I wasn't very impressed. Are there any good/reasonably priced bluetooth adapters that you've had luck with?

The blackberry audio gateway has been reliable for me and sounds decent.

Hmm maybe... not really a fan of having to plug that in, in addition to my stereo. I'll keep it in mind. Any others?

ebay smartdock clone

Be careful. I bought one of these on Amazon a while back...

...and I realize it might not be the same exact thing, but it looks similar in construction.
About 2 weeks after I started using it, it started shorting out and sparking! I was lucky that I was right beside it when it started happening and got my phone out of it before any damage was done. The problem was with the wiring / circuitry in the base of the unit. I threw it away immediately.
So, hopefully your will work a lot better, just be careful.

Thanks for the info. I usually buy stuff from DX, so I'm quite used to opening and doing a good quality check for every item I buy before using it!

I got the item, it works good and the build quality is good.
BUT, when you connect an external power supply, the power to the usb host port gets disconnected and the usb lines get shorted. So you can use either the USB OR the HDMI. There are 3 relays inside the device; by disabling the top one you can do the 500ms short trick and get the HDMI + USB HOST + CHARGING features, but it takes some effort.

Are you able to use or make a charge only cable (only 5V and ground)? That way the USB data lines should not be affected if the charger shorts the data pins.
Or is the one of the relays shorting the data pins inside the adapter?

Sorry, maybe I didn't explain correctly. The adapter shorts the phone's usb data pins, everything else is untouched. A delay circuit is implemented too, so it looks like they tried to do the 500ms trick but failed miserably so they sold the dock as is.

has anyone got any further with this project? I have an original Samsung smart dock and have now got the hdmi converters but nothing is shown on the lapdock screen. The adaptors and lapdock work fine as I have had it connected to my sky hd box?

Hi, did you try the adapters with a TV? My adapters work well and send a (distorted) image to the lapdock..

Yes I tried them both ways as an output to a tv and also an input to a moniter

looks pretty interesting. huh

CONFIRMED working 3.5 audio adapters

I'm starting to see a number of USB-C to 3.5 headphone jack adapters on Amazon, though a great many of them have less than fantastic reviews and many reviewers indicated they don't work for specific phones. I recently saw one that was specifically indicated to work with the Moto Z, so I went ahead and bought. It came today and I am able to CONFIRM that it does indeed work with my Verizon Moto Z Force phone.
https://www.amazon.com/gp/product/B01N7R8PWO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
The USB-C adapter seems to fit well, and I'm getting audio from the Google Music player in both ears just fine. Just thought I'd share my results in case others were looking for working adapters. If you found one that definitely works with Moto Z as well, please share it here.

I'd be interested in finding out if anybody finds one which allows charging at the same time (some sort of USB-C to 3.5mm + USB-C adapter). Otherwise, my phone is useless on a road trip (running Waze eats the battery quick, and I like to listen to music via Aux In). I know that the Car Dock Mod allows this, but that's via the Mod adapter on the back of the phone and I need to use a Universal dock (wife uses an iPhone).

FWIW, if you have a wireless charging mod, TILT makes a universal car dock with wireless charging: http://www.tylt.com/car-products/capio-car-mount
That'll leave the port open for the 3.5mm adapter. Waze will probably still eat faster than wireless will charge, but it should extend the time significantly.

I should probably read posts before responding to them. Please ignore. :]

To me it does. I don't want to carry it everywhere with me to get potentially lost or mangled in my pocket. I'd rather leave one at work, one in the car, and one at home.

I see. I actually only use mine in the car now for the aux input but otherwise I've already converted to Bluetooth headphones unfortunately. And no, not beats. Beats are terrible.

I found what claimed to be OEM Moto cables on Amazon and ordered a couple, but they are currently unavailable. I paid $7.58 each.

Kill your pains. 2 in 1 Hi Res Audio + PD Fast Charging adapter By Soulsound

Everyone knows normal 3.5mm audio adapter are not fit for Essential phone due to DAC chipset required. But when you are listening to music, you cannot charge your phone.
Now i recommend a 2 in 1 adapter for you!
What's special?
1. Hi-Res sound quality with a qualified DAC - 96KHz/24 Bits
2. Max 3A PD fast charging
3. You can do 1+2 above at the same time
Here is link for you:
https://amzn.to/2mi2BXL
You will never stop the movie/game on your Essential and pull off the headphone, put on the power and continue with a speaker again.

Thanks for sharing , I ordered one and it works

I'd like to see a video review and some photos of this if possible, the way this post was written sounds like an advertisement of your own product, or a product you got for free from the manufacturer (no offense). Also wondering if it's fully USB-C spec compliant so there won't be any voltage issues when using it.
Edit: Looking at OP's past posts, he is the seller.

Happy to tell you, i developed this product, but sell by my friend.
I am open to collect all issues to improve it and listen to public what else they need.
Due to this product needs to be different with normal 2 in 1 usb c adapter (without DAC), the inside design is different. That's why all other 2 in 1 adapters cannot work with external DAC required phones, except for Moshi's. They are totally 2 different stories standing on development point.
For normal usb c adapters, the resistor lays in usb c end, however for this kind of adapters, the components have to put on the motherboard. That is to say, the motherboard will take all the risks and devices won't. The motherboard is 3 inch away from your phone, the heat won't affect the phone.
For voltage issue you are concerning, 5V comes out from power supply all the way, 2A charging into phone. One thing i have to mention: use original power supply to charge!
You are welcome to ask other users from another thread below who got this adapter!

I actually purchased it to test it out. Audio quality is definitely better than the included 48kHz adapter, but I'm running into a problem with it right out of the box. There's a pulsing clicking/popping noise that can occasionally be heard at a low volume in quarter second intervals when headphones are plugged into the adapter and you're on a screen with no sound playing (volume of the phone has no bearing on this) There's also some static when switching between screens with no sound. The OEM 3.5mm adapter doesn't have these problems. Also, the clicking/popping noise can also be heard when the adapter is plugged plugged into the wall with USB-C but not plugged into the phone. So it doesn't really matter where it's plugged into, but if there's a power source, the noise is heard. I'm thinking mine may have been a dud, but would like to hear from you or the seller on wether or not this is a normal occurrence. Sent an email to your friend, the seller, yesterday, waiting for him/her to get back to me now regarding getting a possible replacement.

2. plug the adapter to phone
3. plug headphone to adapter
waiting for your report on replacement.

Thanks! I'll try that from here on out. I realized I used the wrong words to describe the noise in my last post, the sound is actually more like a digital beep. It doesn't sound like distortion (well, the static when switching screens does), but more like something you'd hear from an error message popup in rapid succession.
The product you developed is very good other than this though. The audio quality is better than the OEM adapter and charging is fast. I'm excited to use this as a part of my daily routine!
I did have some observations regarding the design though if you'll hear me out - especially in regards to the cable you used. The cable is very flexible, which may make it more comfortable to use, but I have doubts on how well it can hold up. In my experience, the thiner and less rigid the cable, the more likely it is to fail. If the cable was more rigid and half the length it may hold up longer. I'm sure you have done more testing than I have in this regard though, so after a few months of use I could give you some better findings.

Thanks my friend. Your voice is always important to me.
For the sounding like distortion when switching screens, lets test the replacement;
For the cable, don't worry, this is best cable we are using. My partner factory is a professional cable manufacturer for 10 years and they has all kinds of cable. This one is the most expensive one. Check the copper inside by cutting it off! Come back to me within 1 year if the cable has problem.

I actually got the replacement very quickly, and I haven't noticed the beeping noise again yet, but the static/white noise is still there when I switch screens. It doesn't happen with the OEM adapter, but it's something that's present with this one. I tried 5 pairs of headphones and found that it varies in intensity depending on which pair I'm using. The best pair I used was a pair of Nox earbuds (discontinued brand), while the worst were JVC. JBL, Xiaomi, and TaoTronics all tested about the same. When switching screens/apps with no volume playing, there's a initial pop of static, followed by a second or so of white noise before it goes away. The Nox buds were the only pair of headphones I tried that only had the initial pop (no white noise following), and at a lower volume than the others I tested. It's almost as if it's trying to pick up on sound that should be playing on the new screen, but once it can't find any it gives up. It may just be a device specific problem as I haven't seen anything regarding this on the Pixel thread, and it's not something serious that will make or break the product, but it is a minor annoyance. Since the replacement had the same problem, I'm assuming it's something that will be true for all stock.
Edit: After a few days the beeping showed up on the replacement as well. Oh well, it still works great if sound is actually playing, but if you're like me and just have your headphones plugged in all the time, it's not something that would replace the OEM adapter (for the 3.5mm adapter only).

Thanks My friend,
It is really a helpful review from you! I have asked other testers also using an Essential phone but they don't have the problem like yours. However, as long as you find problem, i have the responsibility to find them out and fix it. These days i have been looking for several essential phone users to test and waiting for there reports. Meanwhile i am also asking my team to simulate your case and fix that problem, but that need time. Although the phone model is same, it needs time and lucks to re-appear the same problem you have.
Thank you for your wonderful report, i won't ruin your hard work.

It may just be a device specific problem as I haven't seen anything regarding this on the Pixel thread, and it's not something serious that will make or break the product, but it is a minor annoyance. Since the replacement had the same problem, I'm assuming it's something that will be true for all stock.
Edit: After a few days the beeping showed up on the replacement as well. Oh well, it still works great if sound is actually playing, but if you're like me and just have your headphones plugged in all the time, it's not something that would replace the OEM adapter (for the 3.5mm adapter only).

Works great for phones with no headphone (3.5) jack. I have the Essential Phone and being able to charge and listen to music/movies via 3.5 jack at the same time has been awesome. The sound is just as good or better than the USB C to 3.5 jack that came with the phone. This should have been included in the box when the phone arrived. I loaded Viper up and it sounds even better. I will be buying again for my other phones..

Thanks so much Johnny for helping test!
I am also looking forward to know whether you have the same problem with the friend in above comments? He is also using an Essential Phone, but he found some problem when using.
I know you are busy, take your time and test it for more days before reports.
As a developer i am eager to kill all imperfect things and make it zero issue to everyone.
Thanks!

I have not had the pop sound/noise when switching apps or anything else. It really has been great. I am rooted running viper though.

Thanks My friend,
It is really a helpful review from you! I have asked other testers also using an Essential phone but they don't have the problem like yours. However, as long as you find problem, i have the responsibility to find them out and fix it. These days i have been looking for several essential phone users to test and waiting for there reports. Meanwhile i am also asking my team to simulate your case and fix that problem, but that need time. Although the phone model is same, it needs time and lucks to re-appear the same problem you have.
Thank you for your wonderful report, i won't ruin your hard work.

I'm going to see if I can record the sound somehow. I'm curious as to wether it would play when connected to a speaker - I'll try that next. Kind of odd that I'm the only one who has reports of the extra noises. 2 out of 2 adapters I've tried both had the problem though, so I don't think it's a coincidence. I've also tried the adapters on 2 different Essential Phones and had the same results.

Finnaly an adapter that looks like it works as advertised .
Do you maybe have an EU store too, so that I don't have to pay an arm and a leg for customs and shipping?
Can't wait to enjoy charging and watching a movie at the same time!
To be honest, manufacturers should include an adapter like this by default if they decide to remove 3.5mm port and DAC.
Kind Regards

For voltage issue you are concerning, 5V comes out from power supply all the way, 2A charging into phone. One thing i have to mention: use original power supply to charge!

So this adapter charges at lower output than OEM (3A)?

Yes lower than 3A for smartphones. Only when you use it on laptop like Macbook will reach 3A max.
For PH-1, the max current reach 2.5A max. If you have facebook, i can send you a video showing the charging voltage/current/watt
