Which android phone is supported by car's audio system (Iphone works but it is too expensive for me) . My goal is to play mp3's from my phone via usb. I tried Google Nexus 4, Galaxy S5 and each time I got message "not supported device".
I like to listen to podcasts. My goal is to setup a phone to download podcast automatically and play thru the car's system. I want to control the files using car's audio system. Currently I do that thru the aux cable, but it is a pain because I need to take my eyes from road , when I change the mp3. I need to concentrate on the phone's menu ( looks like Im texting = ticket) to change or skip the file.

At this same time I could use the device as MPG gauge (with Bluetooth dongle).
