i bought the car about 5 months ago and i love it, accept for when the dash unit wont change modes into cd, the radio works accept the mode button doesnt work so i cant play cds, volume control and everything is working, the previous owner had the radio replaced about 3 years ago because the factory unit took a dump, does it need replacing? or is there some kind of reset i should try first? another question about the bose system, can i install an aftermarket unit and still run the run the bose amp and speakers?? im sure its in the forum somewhere but i figured i would ask while on the topic
