Well, I thought I was going to be posting good news tonight, but instead, bad news... and I've no idea what happened.
Hold that thought. I just tried to fire her up and the battery is dead... click, click, click. So I'm pretty sure that's the problem. Surprised the stereo ran it down but I guess I was playing it for quite a while. Too late to jump it, don't want to disturb the neighbors. So I'll report back in the morning. Dead battery. Sheesh.
As Dicktator and others (even myself for once!) surmised, it was the battery. I jump-started it with the wife's car this morning and life is good again. Phew!
I removed my Bose 6CD stereo and installed a new Pioneer AVH-W4400NEX stereo today. I tested everything out before mounting it. Everything played fine, HD radio, DVD movie, Apple Play, all checked out. I was getting ready to put the dash back together while it was playing a DVD movie when it started sort of stuttering, the sound went in and out a few times and then the entire unit shut down. ???
I checked all of the wiring, no loose ends. Checked the radio and amplifier fuses, both good. I unplugged the Pioneer completely for a few minutes and plugged it back in. The splash screen appeared and then it just went dead again. I can faintly hear the little "ding" when the initial warning screen appears and I press "OK" (when it gets that far), but then it shuts down again. I did this a few more times with varying degrees of success... getting to the main menu a couple of times but it keeps completely shutting down, black screen and all button lights out.
The normal door/alarm chimes are working through the speakers just fine BTW.
So I tried plugging the OEM radio back in. Initially I had sound but within about 10 seconds the audio stopped completely. The radio appears to be working, all normal digital readouts appear, time, volume meter goes up and down, but zero audio.
At first I thought my new stereo was failing, but I think I can rule that out because the original radio, which had been working fine all along, doesn't have any audio either, although it doesn't just shut down like the new Pioneer stereo.
So is the Bose amp in trouble? Is there a way to bypass it and just use the Pioneer (if that would work)?
Welcome any ideas because I'm stumped. And pretty bummed.
