Well, i FINALLY got my F700BT installed in my M3 tonight... and all was going well.. radio sound is great.... GPS is great. but then i put in a CD.... it showed me the tracks, and acted like it was playing, but there was NO sound this time.... so i tried another CD.... same issue. first CD was a RW and second was a regular store bought CD... please help ... also, it said (upgrade 2.0 installed!) on the box. and i confirmed that on the software info. whats the problem here?

sounds like you hooked up the antenna lead to the amp turn on wire. change the setting on the deck to power instead of antenna.

Thanks a million that was it! *phew*
