Hey guys,
I just installed a Pioneer 4200-NEX in my car. It has 2 one amp USB ports (one for carplay and one for android auto - so much for UNIVERSAL serial bus). Anyway, I have extra cigarette lighter ports in my car. I was wondering if there was a good way to splice together the power from the high-amp low-heat dash charging with the Android Auto USB cable. This would eliminate any lag since the phone wouldn't get hot. A spider cable must be possible, but I don't trust my knowledge in hardware hacking to not blow the damn thing up without some input from you guys.
Thanks all,
Hope this is the right forum (don't want to break any rules)
Dash charging requires 4amps, so you would need 2 more of those to even try

Hi
Ive got a emtac GPS bluetooth reciever and this comes with an in car charger. The charger lead splits into 2 with one side going into the emtac and the other should go into the XDA II
However the connecting lead is missing. So I need a lead that goes from the split into the bottom of the XDA II - I already have a XDA II power connector that goes into the bottom of the XDA so its just the lead to connect the 2?
I hope I have explained that????
Any help would be great
cheers

It would be very unusual for a bluetooth wireless gps to be supplied with a lead that links the pda with the gps, if you have the car charger for the gps and a car charger for the xda then all you need is a double adaptor for your lighter socket to take both chargers. If this doesnt answer your question then try here and look at all the different leads, if your gps uses a standard mini usb plug then you can use the Fortuna lead to power your pda and gps a the same time. If you are going to be using a cable that links both I wonder what the sense is in buying a wireless gps because it rather defeats the object.
hi
thanks for the response, i can see your point about connecting a BT device to a BT XDA with wires - sorta defeats the object!
However I suppose it is saving on chargers?
I already have a 4 way in car adaptor, but one is taken for charging my phone, one for my BT headset, one for the BT GPS reciever and the 4th can only be used for an actual cigarette lighter, meaning I am one short for my XDA
So if I can get the lead to connect the GPS power to the xda then im fully charged!
My car looks like spaghetti junction with all the wires!

WARNING! CONNECTING ANY CABLE TO YOUR PHONE THAT DID NOT COME WITH YOUR PHONE IN THE BOX COULD DAMAGE YOUR PHONE, YOUR COMPUTER, THE ELECTRICAL WIRING IN YOUR HOUSE, AND IT COULD KILL YOU!
you have been warned
Soooo I recently stumbled across this thread http://forum.xda-developers.com/showthread.php?t=744636&page=3
that states that if you short pins 4 & 5 on a micro USB connector and plug it into an HTC Desire, the phone will automatically go into car dock mode. as luck would have it, I happen to know that this is the same method that is used to trigger USB OTG on devices that support it. The wheels in my brain began to turn... $7 and a few days later I came up with this:
MICRO USB HOST ADAPTER + A BIZARRE A TO A USB CABLE = A CHARGING/DATA CABLE THAT TRIGGERS CAR DOCK MODE!
I have tested this on my G2 using Virtuous G-Lite 2.0.1 and it works perfectly, but YMMV.
I got the USB host adapter here
http://www.amazon.com/Micro-B-Adapt...3?s=electronics&ie=UTF8&qid=1328093895&sr=1-3
and the A to A USB cable here
http://www.amazon.com/StarTech-com-...3?s=electronics&ie=UTF8&qid=1328094123&sr=1-3
Just in case you haven't already figured it out you just connect the female end of the OTG adapter to either one of the male ends on the A to A cable, then use the cable as you would any other charging/data cable in your car. the only difference is that now your device will automatically switch into car dock mode when you plug it in! you could also connect this cable to a dock that has a female micro USB connector on the back (like the G2 OEM desktop dock here http://forum.xda-developers.com/showthread.php?t=1473718) and create your own car dock!
an extra word of warning, DO NOT USE THE A TO A CABLE ON ITS OWN FOR ANYTHING! this is a non-standard conforming cable that would damage any two USB devices that you attempted to connect with it. I have no idea what it's intended use is on it's own, but don't think that it is the same thing as a USB data transfer cable (transfer cables have a chip inside the cable that makes the two connected USB host devices see each other as USB slave devices. this A to A cable is just a copper wire)
Nice, I didn't know people wanted this. I got a premade cable. Off ebay that triggered car mode no mods needed and it was a buck. Lol

Any idea about standard dock mode? I know the official tmobile dock auto opens a desk clock.

My guess would be that the cable was not intended to trigger car dock mode, it was just poorly made. a really bad soldering job on the pins would short pins 4 & 5 and do the same thing. Other people have reported this same behavior when they buy low end cables or get water in their micro usb ports.
I tried this and it seams to work but all it does its launch tunein radio, any idea how to change it to other apps such as torque? Thanks
The short thing does work. I my self stumbled on to it while repearing a aftermarked charger .. I opened up the mini usb side and it had a resistor on jumping pin 5( - ) to pin 4 . With the resistor on it charches with the resistor bypassed and just jumped to pin 4 it goes in to car dock mode. Also my friend got a samsung infuse and came with a hdmi dongle usb, so out of curiosity hooked it up to my g2 and it whent to car dock mode

Thought I would share my experience so no one else repeats this. I bought a micro usb ethernet device so I can hardwire my nexus player. Connected it to nexus player and it did not work. The ethernet device had an extra power cable for it. Thinking it may need more power, I foolishly connected power cable. Now nexus player doesn't even turn on (powerlight off). I'm afraid I may have shorted the motherboard. I was able to open up nexus player using guitar pick....but don't even know what to do. Spent alot of time tinkering with it too. So sad as I am now left with an oversized hockey puck Lesson learned.
Look for black marks or brown you can also take a multimeter and check components you would want to check any smd fuses first then trace back from the USB plug. I don't imagine that killing the whole thing. Does it respond at all?

Did not see any black or brown marks. Unfortunately it does not turn on at all. I'm getting desperate and am thinking of buying a new 12v 1.5 amp adapter. Do you think that may work? Thanks for your input.

I don't think so if hypothetically the Ethernet adaptor delivered voltage to the usb port on the nexus player and now with just hdmi and power plugged in it wont turn on i doubt a new ac adapter will fix anything.
You can check your current adaptor if it is broken by using a multi-meter to see if it is providing 12v.
Can you link the Ethernet adaptor you tried to use? And what ac adaptor you plugged into it.
I can think of a few things that are not what you think they are that have ac adapter sockets. But i cant think of a single Ethernet to usb adapter that takes 12v all the ones i know would be a 5v adapter at most with more running off usb power...
I would look for a replacement nexus player not just the ac adaptor... Check target or walmart first they dropped them down to 20-40 when they got discontinued i wish i had picked up a second one now... i got 2 of the game controllers one for 29 one for 10...

Yeah it is not the ac adapter. I tried an equivalent 12v 1.5amp and it still didn't turn on. When plugged in if I put my ear next to nexus player....I do hear a faint hissing sound, so there is some activity going on. I went out and bought a multi-meter and did what you suggested to check components tracing back to usb. This is all new stuff to me but I found that there was 0 reading on a tiny black rectangular module that has P15 on it. I'm assuming that is the smd fuse. Not even sure where to buy a replacement one. Tried to procure one from old computer board but was unsuccessful. Will search some more online on where to buy one and learn how to solder.
The ethernet I bought was http://www.ebay.com/itm/White-Micro...851881?hash=item567e4840e9:g:QEkAAOSwvt1WRYAO I wasn't thinking and plugged a 12v 1amp into it.
Only nexus player I see being sold is on ebay. I'm being persistent on reviving this one only because I spent alot of time on it already and am stubborn....lol But I will give up when I replace the P15 module and it still doesn't work. If nothing else at least I'm learning...so thank you.
Yes the little thing labled p15 is a fuse im about 80% i think p5 is also a fuse... you should get 0 resistance on them and they should be able to pass current switch the meter to Continuity mode and if the 2 probes are connected it should make a noise put them on either side of the fuses if they dont pass current they are likely blown as for replacements dangerous method would be to replace them with a wire otherwise they should be around .50 cents each from what i could find they are self resetting type so they should reset once any residual voltage is gone.

Ever since getting my Pixel 2, I've had trouble finding a USB Type A-to-C cable that works reliably for charging and/or data connections. Now the one that I've been using for Android Auto in my car seems not to work consistently, and I'm leaving on a trip in a week where I was really counting on using AA for navigation.
Can anyone recommend an Amazon-stocked cable that is known to be suitable for this purpose without any problems? Seems like a simple thing, but apparently not! I'd really like one that clicks in positively, as well as having the proper connections, wire gages, etc.
Can anyone help? TIA.
This works when connected to my pc and a charger but is not fast charging because fast charge only works on c-c cables.

Thanks. I found it on the US site and it looks good. Would be nice if it were a few feet shorter!

A slight drift in topic. But has anyone had experience with the newer wireless Android Auto head units? With the units themselves being new, and with only a handful of compatible phones out there, there's not much info on the interwebs yet.

I use this one, the 3-feet version. It works fine, just the right length. It is a two-pack, so you can use one for your car and one for your PC.

Here's what I use in my car. Haven't had any issues with it since I got it last year.

I've used several. Here's my current and is my favorite:

This is better than the Anker ones I've used and the iOrange ones (which seem to get loose quickly, and especially in the summer heat). All are better than the stock OEM one from my original Pixel
I've used these in my truck with a 6P and my Pioneer head unit:

Three lengths in one package, very sturdy cables, never had a connection issue.
Change USB settings to enable Android Auto
Hey everyone,
I just got Android Auto installed via my Mazda dealer on my Mazda Connect infotainment system. Using my Google Pixel 2 XL, it was working fine for two drives and then stopped out of nowhere. I thought it was the USB 2 to USB C cable. Ordered 3 cables, and they still weren't working. Then I lucked out when trying to clear my phone's system memory by finding the USB settings and now Android Auto is working just fine with my cords again. [Facepalm]. At least I have several backup cables now. The steps I took are below (if you have the correct cable):
1) Swipe down on Android to access "settings" cog [bottom right typically]
2) Type "memory" into the 'search settings' bar at the top.
3) Select "Memory - System > Developer options". . . It should be the first result after you've searched.
4) Scroll down to and select "Default USB Configuration" . . . Under the 'Networking' section.
5) Select "File Transfer"
Might have to reboot, but that was it for me! Hope this helps.
I bought a BlitzWolf BW-TC9 and I have absolutely zero issue. I had disconnect issues on my OnePlus X with every cable I tried. I was afraid that the situation will be the same with the Pixel 2, but no, it's fully stable. If you are in Europe you can give it a try.
I picked up a Lenovo Tab M8 from walmart (Part number: ZA5C0045US). It comes with a small dock that charges the table via a two pin connector.
I was trying to set this up with an OTG cable so that I can attach a high end sound card. I notice that once I plug the OTG cable, the tablet stops charging via the dock. It's like OTG and charging is not allowed at the same time.
I also tried making my own OTG + charging cable (with a 10K resistor between the ID pin and ground), but it seems that the OTG function will not work unless the ID pin is grounded. I know that other devices allow for OTG + charging when the ID pin has a resistor to ground with a certain value.
Is there a way of finding out if lenovo tablets allow this? If so, where can I go an find out what type of resistor value this tablet will detect as allowing the function of OTG + charging?
Also, this tablet is rooted. Is there a software based solution like my old Nexus 7 (2013) where you could enable OTG + charging?
I've been at this for a couple of days now, so any help is greatly appreciated.
Hi,
Have you had any progress on this? I would like the same function.
Doing some reading though. I think a 10k resistor is too low, normally seen 64k or 100k
Hi, I just signed up to leave a reply here. I also was looking for a replacement for my slightly outdated Nexus 2013 in my car and stumbled upon this thread. So got a used M8 (TB 8505F ZA5G0038SE) and gave it a try.
With a 10k (measured 9.8k) resistor between ID pin and ground, OTG and charge works perfectly, without changing anything in software. With a 2A charger, battery charging is pretty slow, but the battery doesn't drain while using navigation and music (contrary to the Nexus )
So, for me it is a quite good solution.
Thank you for the info guys
I also have a TB 8505F and needed this function in my car.
For me the 10K resistor works, now it both charges and I can use my accessory (OBD2 reader)
Before this I tried a 100K resistor and that did not work so I had started to give up.
Just an update, maybe someone needs the info: I tried to make a second Y-OTG-cable with the same components, and it didn't work. Charging went on and off, no otg function. I decided to play again with the resistor values and it worked again with 12.9k. Maybe there is a certain range, which the second cable was slightly out of.
Hi All, i just bought the same tablet for similar purpose and i was wondering if when the cable is built using the 10k-12.9k resistor, i can still use the docking station that it comes with>? has anyone tried it out like this?
