mytouch 4g and a car stereo

My wife's car stereo got stolen a few weeks ago. When shopping we saw a new stereo with a usb port. We got it, I was thinking it would be great, one cable to charge and play music at the same time (Instead of an audio cable and a cigarette charger) We plugged in the usb cable which came with her mytouch 4g phone plugged the mini usb into her phone and the usb into the stereo and set the stereo to usb and the mytouch played music over it's own speaker... I tried it in charge only, disk storage, and usb tethering. None of them worked. When I put it in disk drive mode it wouldn't play any music at all, instead saying to mount the SD card. Can this be made to work?
(NOTE: It's a Sumas Media SM-868CD car stereo)
Thanks

you'd have to contact the manufacture of the stereo.

We decided to take the stereo back. I was just doing a final check to see if maybe there was a setting I wasn't thinking of on the phone. Oh well...

that would NEVER work. the usb on the mytouch4g is for charging and data ONLY. you would have to buy a stereo with an AUXILLIARY jack. then you need an auxilliary cord that is 3.5mm on the phone end and whatever size you need for the stereo. im my case, just a double ended 3.5mm cord. cost me like $2. plug one end in the HEADPHONE jack and the other end in the car stereo and PRESTO, you have music through your phone to your stereo. (just make sure your stereo is on AUX mode)

best way to have done it for that would when you plug the phone into the stereo it will ask to toggle the usb for the SD card. just set to usb disk and hopefully the stereo picks it up. once it does then just browse through the stereo for the music.

That depends on the stereo, some of them are are made for either generic file grouping or iOS products.

Exactly, My car stereo 'sees' my MT4G via USB connection just fine, it does depend on the stereo though. I have the Sony MEX-BT3800U.

You're going to need a name-brand HU for it to be able to browse the phone's sdcard. Sony, Kenwood, Pioneer, Alpine, etc. I'm personally a fan of Alpine.
Or you do it the easy way and just buy a cheap adapter to convert the cd changer port of the HU to a basic aux cable.
Like so.

Cables for "mirror display" via Red-White-Yellow female jacks? (Infiniti G37 dash)

Cables for "mirror display" via Red-White-Yellow female jacks? (Infiniti G37 dash)
Has anyone successfully ran their Photon Q in "mirror display mode" via the micro-HDMI out port?
What hardware/cables are needed and can you provide an internet link for vendor/price?
I have a Infiniti G35 sedan and my DVD screen will take video/audio input from the three female ports in the armrest which are Yellow-White-Red.
I would like to display the Photon Q screen on my Infiniti G's DVD screen and hear the Photon Q audio through my Infiniti's G speakers.
Here is a pic of the center console female ports:

Thank you in advance for any assistance.

FYI, the audio would be really easy. You can just use the 3.5mm headphone jack with 2 RCA plugs on the other end, and audio is done.
Video... Not sure how that would work. Either way, that's 'composite' - so it'll look pretty awful.

You can get audio via the jack on top, and forget about Video, unless you use a really-expensive converter, as the HDMI video that comes out will be 540P YUV, whereas that composite input in your car is 480I Y/C.

I don't need Hi-Def video. I just want the Photon's Navigation displayed on my car's dash display.
How much is a converter and where can I get one?
Will a cable like this one below even display the video on my dash? How will it look?

You don't have component in (which that cable is). You have composite input to the stereo, you'll probably need some sort of converter while hoping that the phone doesn't require HDCP (I doubt it). Let us know!
Edit: Something like this might be exactly what you would need.

i have the same car 2009 also s4 i9505. i have Nokia N82 video cable but no video shown in my screen only audio so which cable can show the video for infiniti G37 screen in brake position

Charging + analog audio over USB

I'm interested in getting a car dock, but so far all of the docks I've seen only connect to microusb to allow you to charge your phone. If you want to get audio out, you have to connect a cable to the 3.5mm jack. Has anyone seen a cable or adapter that allows you to both charge from a USB charger and has analog audio out so I can connect to my stereo? I am aware that microusb does not provide analog audio out, however the android accessory development kit does seem to support audio over usb, so the cable would need to have some DAC built in. However I can't seem to find any. The only option I've been able to figure out would be to buy a USB DAC intended for a PC, connect it via a USB OTG cable, and splice in my charger. But this seems cumbersome and expensive.
Thoughts?

This is something I am interested in as well, however, I really don't think there's any way a dumb adapter could accomplish it without a DAC, like you said.
Probably the smallest option would be something like this, but still expensive; and since it'd be OTG, probably a pain.
My current attempt is to DIY a POGO dock (using the contacts on the back of the phone) out of one of these.
According to some work these guys did the contacts can function for charging and audio out.
I'll let you know if anything ends up working.

Well, I got all my parts in... and ended in failure
(I forgot to take pictures during, but here are some after the fact...)
I started with a Kidigi car dock:

}
It holds the phone fairly securely:
But there are three problems:
It looks to have been built for the international version, since the usb plug is about a millimeter out of place. This isn't a problem... unless you're trying to line up tiny pogo contacts.
If you remove the usb plug, the phone falls out of the dock, damn!
The usb plug is modified so it triggers car mode when plugged in.
Anyway, I decided to forge ahead.
I was able to determine where the pogos go by lubing up the back of the phone and pressing it into the dock with some duct seal in between.
The construction of the dock was extremely convenient for this project; it was made of three pieces.
Two pieces are screwed together, and one clips in depending on whether or not you have a case on your phone.
I drilled the clip in piece to just allow the end of the pogo through, but not the whole thing.
Then I drilled the other two a bit bigger to fit the whole pogo:
I put the pogos through:
And epoxied them in on the inside of the two screw-together pieces:
All the connections worked!
I temporarily tacked on some wires to the pogos and was able to charge the phone.
However, even after playing with a ton of different resistances, I wasn't able to convince the dock to output audio from the other contacts.
I didn't know if it was because I was on a sense 5 rom, so I tried cleanrom 6.5 (basically stock), and JB aokp... no luck.
Long story short, I'm just going to use the dock as it was intended and deal with having two wires coming out of the phone

I try this one - http://www.ebay.com/itm/Black-3-5mm...Phone_PDA_Cables_Adapters&hash=item25825f2273
but no audio out on the 3.5mm jack

Car head unit as Galaxy S4 docking station

Hi,
If you know a bit of hardware you will find this usefull. The idea for the dock started quite simple: control the phone from the steering wheel using the USB port. Once that was ready the maker in me said:
"Hm, that is good but how cool would be to also charge the phone ... yeah USB Host and Charging does not work together but there have to be a way ..."
and once that was done again:
"Nah, it is crappy to put one cable for USB and another in the headphone jack for audio ... how cool it would be to channel the audio through USB also?"
And here it is how it all ended up (+lots of info how it works and how to build your own):

Too complicated for me, but what USB DAC are you using?

I believe it is plantronics brand, do not know the exact details ...it came broken in half (literally)
anyway - any usb dac will do (USB DAC == USB Soundcard) just check with OTG cable that you phone will recognize it and play musing throught it.

Cool stuff. Like mentioned before .. A bit too much for me to take on as I don't have enough free time to set up. If you got yourself into making and selling these then I think you'd be on to a winner. Thanks anyway.

If you are willing to:
* loose the ability to control the phone from the steering wheel
* loosing your cigarette lighter socket (a car charger should in there)
* have another cable hanging around for the car AUX
you may take a look at theiBolt docks - they can also charge the phone plus emit sound using the USB port (you do not have to connect another cable in the headphones output)

Cheers dude will look into it. Having steering wheel controls would be sweet though.

Aukey Bluetooth 4.1 Wireless Stereo Portable Mini Lightweight Gym Earbuds help me run

I recent brought this Aukey Bluetooth 4.1 Gym Earbuds for running. When I choose the very songs I like best and then ware the earbuds, I could run more than an hour ( I could only run half an hour before...) I used to use wired earbuds when running and it's really annoying to see the long wire flying crazily in front of me...
Ok, here comes to the nice earbuds.
The right side earbud has the volume button on the front and it's quite long so you can easily find the volume up and down when working out. The mic opening is positioned below the volume down button.

A little thing I dislike: the charging port really needs agile fingers. But mine are a too fat and clumsy...:crying:
But I guess there are only green ones of Aukey earbuds. I do hope there could be some other colors. Black, blue, yellow...Haha...

I'm too lazy to run, so any earbuds that can help me to actually do it without breaking a sweat would be a good thing.

Haha, I am also very lazy to run, that's why I should listen to music when I run. That really could help divert my attention from tiredness. But I like it when I sweat a lot. That's a good sign showing that my fat is burning, and I will soon loose weight.
Come on, let start running! You will feel like gaining more energy!:highfive:
