Hello you, I’ve been proud of a 95 Pontiac Firebird Cabrio 3.4l / 140 HP for a few days and from now on new here. Now to the actual question: Who has absolute clue regarding above mentioned Autocass.radios. 1. Can I run a second car radio (MD/CD JVC) parallel to the original. Would you like to do without the original but also not my minidisk. If possible, then how ? 2. If not possible, can you exchange the original for another one ? If yes, how ? would only sc had, since then one would have to give up the steering wheel remote control,or ? Thanks first, and with the best regards from the Holledau (Bayern), NewCrazy.
