I have a 2006 maserati quattroporte I have no sound from radio and it resets every time I start car brand new interstate battery the biggest one they make and the one recommended for those cars. Also can not get it to program have disconnected the battery and followed reset . Glove box only stays closed when key is on or car is running opens and won't close when key is in if position. Any ideas??? I've worked on cars for 20 plus years but can not find wire diagrams for this car, have replaced alternator before the battery bc it was not charging but now is and has the correct brand new battery and has not had and problems with voltage drop.
Sounds like the accessory wire for the stereo is not connecting. That should save the radio settings. When you changed teh battery, you may have loosened one of the wires on the positive plate that sits on the positive post (at lease on the 07 QP).
I'll double check that but never really did anything to make them lose, also there other problems like the glove box opens and won't close when car is off and the system will not program no matter how many times I do the procedure.
