Can we use USB for audio on the RAZR, so I could just plug in one cable to my head unit in my car and listen to Pandora and the like? Are there any ROMs that support this?

I would also like to know if this is possible and if so how to do it

I gotta say I have never heard of this. I'm gonna go out on a limb and say it's not possible. Someone can correct me if I'm wrong.

Oh, it is possible... There are several threads where people want to use their nexus 7 as a head unit and plug it in as USB audio. But afais it is a pretty heavy modded ROM. Would be awesome to only have to plug in one cable in my car.

mounting it as a usb device (like plugging a flash drive/external) should work if youre headunit supports it..the pioneers i've had supported this feature.

Pandora and spotify (what i use) are a different story. I would say that mostly the apps would have to support it like the camera transfer (picto bridge thing).

It would not only be cool to be able to charge and play with 1 cord, but to be able to change songs with the head unit where it auto starts and stops as soon as the car is turned off rather than having to unplug it and press play when it's plugged back in (1st world problems... )

Well I stand corrected. Maybe a Dev can jump in here with more info??

I have a really high end pioneer and when I plug in it says no device connected so there must have to be some mod because stock don't work and multiple ROMs don't work either

If you look at the razr car dock that can do audio over usb. I know because I have one...

I use Pandora and that's what I was wanting it for... That and Google music... And Doggcatcher. The only kink that comes to my mind is if the USB on the head unit only outputs 500ma. Would that be enough to charge the phone and stream on 4g?

I purchased the official motorola navigation dock and it charges your phone and sends audio through the usb cable. I use Power Amp, Pandora and even Youtube to send audio through the usb cable and it pumps the sound through my system. There is no special rom needed, its baked into the Motoral based ICS roms. I have used the stock rom, Eclipse and currently on ArticHD and had no problems. I have flashed JB roms and this functionality is lost with all 3 that I have tried so I guess I have to wait for a moto based JB rom to get this functionality back.
