connecting Galaxy Nexus via USB to car stereo (Sony XNV-660BT)?

post #1 of 4
Thread Starter 
I'm pretty sure I'll be upgrading to the Galaxy Nexus when Verizon releases it. After doing a lot of research, it looks like it uses the MTP protocol which means USB mass storage support. A few articles I read said this means no USB audio playback thorugh your car's stereo. Namely, this article that states "Instead of UMS, the Galaxy Nexus uses Media Transfer Protocol (MTP), which allows Windows PCs the ability to browse files exactly as they would a normal disk. Sadly, car stereos have't caught up and there are relatively few models that allow you play tracks via MTP."

However, the truck I'll be using this phone in has a Sony XNV-660BT installed. In the specs page, it states "This unit is compliant with MSC (Mass Storage Class) and MTP (Media Transfer Protocol) type USB devices compliant with the USB standard." This makes it sound like my stereo is one of the few that does support it. So I should be able to plug in the Nexus via USB in the back and have all the normal control over it through the receiver that I would have with, say, and iPod, right? I just know that an iPod is fully controllable through the receiver, and was hoping to have the same control with the Galaxy Nexus. I know next to nothing about phone storage protocols, so I just wanted some input before I get my hopes up, then dashed when I go to connect it for the first time. Thanks

I don't think it will be fully controllable. MTP gives you access to the files on your phone but doesn't let you control your phone through it. You will be able to play whatever music files you have on your phone through your stereo but you won't be able to stream anything from the cloud. The iPhones proprietary connector is what Apple uses to give third party accessory vendors the ability to control the iPhone. Google hasn't made android able to do this frown.gif

thanks for the info. I plan on mounting a phone holder right next to the unit anyways, so I guess I'll just have to reach another 6 inches to control my music. but at least it sounds like I can play it through USB instead of 3.5mm or bluetooth (so I can charge at the same time).

well I finally got to swap out usb cords in the back of the unit, and when I plug in the phone, it says "USB device not supported." boo. at least bluetooth works perfectly, and the USB charges. but everytime I plug it in to charge, it's gonna switch to the USB audio input and tell me it's not supported. then I have to manually switch back to bluetooth input to keep listening to music. kind of a hassle, but better than dealing with a 3.5mm I guess. if anyone has any suggestions, please let me know
