Connect android phone to car usb to play music

This is not for a prelude but is relevant for any car stereo with usb.

I have a Samsung Galaxy S3, is it possible to play music from the phone using the micro usb port to a car stereos full size usb? I don't want to use the headphone jack as the sound quality is poor.

Anyone on here done this?

Depends on your headunit usually, and how it sees your phone.
It maaaay see it as a mass storage device and allow you to play stuff.

This ^ although any recent phones mount as an MTP device, rather than mass storage, I can explain why they do this but I doubt anyone would care.

I'd just buy a cheap USB memory stick tbh, you could get a slimline one and leave it plugged in:

Mass Storage is a really basic way of mounting storage but only allows access from one source at a time. This meant that when you plugged your phone in to a laptop for example, the laptop could see the storage on the phone, but the phone itself no longer had access to the storage.

MTP stands for Media Transfer Protocol and allows the same storage space to be accessed from multiple places at once. This means you can plug the phone in, see all the files on it and the phone can still see the storage at the same time.

Unfortunately a lot of USB enabled systems simply assume Mass Storage (aka a pen drive or similar) and so won't mount an MTP device - I would suspect this includes most car systems.
