I was able too, conected my HD2 to my USB Audio CAR.....but all, audio files play mixed.....ok no problem......but first play the phone ringtones.
Someone know a workround or tip, to USB CAR put the ringtones on the end of the list...or a way of the USB car system, not reconize them.
maybe a edit on the ringtones folder?
OR delete all ringtones, and just have the one or two, that i use....thats it!
I can handle a mixed playlist....but without ringtones.
