I just bought a Honda with a USB port for audio. The manual lists iPods/iPhones that work and says USB memory sticks also work. And on a Honda forum I see people with Android phones say the car recognizes the music on their internal memory cards. But when I attach the N900 it just says "unsupported" (in either mass storage mode or PC Suite). I know this can't be known for sure, but I am curious if anyone could suggest a reason why the N900 would not work? Seems like mass storage is pretty standard...I guess I am lucky that it does appear to charge the phone, so that's a plus.

[Also, just putting this 'out there' for others who may wonder if it will work. ]
