I'm trying to install a Sony MP-80 head unit, CD Changer and speakers. My wife is pissed off because of all the time I'm taking and I'm pissed off because things are not going right.
First question: when you install an aftermarket head unit, is it normal to be able to use the CD eject function, even when there is no key in the ignition? I think I remember being able to eject CDs from the Monsoon CD player but I can't remember. The stereo won't turn on without the car running or in accessory position. The reason I ask is because my battery was dead this morning and I'm trying to figure out whether it was because I worked on the stereo for about 5 hours yesterday without disconnecting it (D'oh!) or if the head unit drained the power overnight. I'm pretty sure I wired everything up correctly. The stereo acts the same way as it did in my VR-4 except for being able to eject like I said earlier. The warning chimes sound when you shut the car down. It powers off, or seems to. What do you think?
Secondly, my changer doesn't work or communicate with the head unit. I have the Sony CDX-757MX. It's supposed to connect via the BUS cable and audio cables and just work but no, that would be too easy! It's getting power because the magazine eject works but it's not playing CDs. The head unit says it's not able to connect/communicate with the changer. None of the functions work. It just sits there trying to talk to the changer. I'm going to call Sony on this one. Maybe the changer is defective or I have a bad cable. It says in the manual that they're supposed to be compatible. Any ideas?
I'm working on a write up showing how I installed everything in my 02 Trans Am Convertible and I'm hoping to finish it so maybe the next person to try this will have an easier time of things.
