I just made the switch from iphone to an evo 4g a few days ago and it's pretty sweet except for one thing. It wont play the music that I've synced from itunes. They are all m4a format but that can't be the problem because I've never had problems playing music from my iphone/ipod. I am using the usb jack in the car since i don't have Nav and can't stream using bluetooth. The only music the car recognizes are the 4 default mp3's that come with the phone. Is anyone else out there with a gencoupe having this issue?
