Yes, that's what I was replying to. I thought perhaps her (same as OP radio) problems may have been caused by LED tail lamps or something...Usually not because CANBUS-compliant lighting wasn't an issue in earlier model years. BTW, this thread is about radio issues - specifically the Bose system.
I dont understand why every one say amp .. they must know nothing about gmc and bose... Bcm allow the inside radio module to send a signal to unlock bose amp so that bose amp can output/play speakers.... changed bose amp 3 times nit fixed nothing .. have a after market radio with a can bus that made for bose Acadia that will send that signal to bose amp... sometime sound come back or a creeping sound where you turn off radio and sound stay... when I put factory radio bose that was working I still have no sound... fuse goods 12V there and ground to amp...
HOW TO CURE NO SOUND/BUGS PROBLEM . .. I heard plenty of new gmc models have to call on star to get free update on module software to remove bugs like the no sound bugs... A guy said the dealer Gm tech made a call to on star he put the car on reverse gear while on phone with on star and gave the gmc acadia vin then sound pop back on.. on star did an update on radio module... took less then 10 min ... I also heard sometime you have to reprogram bcm so that he allow bose stock radio or can bus from aftermarket radio to send signal unlocking bose amp output to speakers...
If you read these up posts its just mechanic tech that think they know gmc but they know nothing and figure out sound wont if a amp is burned... ( logic but its bull **** on gmc acadia/traverse/enclave/outlook)
Amp have no problems its software update .. gmc made these bugs so that peoples go repair at dealers and so that Gmc steal many cash$$$$
If anyone else ever has this problem; I fixed it by replacing the amp. It is a very tough job. Tight squeezes, little room for tools, and awkward positioning. Nothing about it was easy. The Amp is located up and behind the emergency brake. Locked in with 3 screws. 2 of them you cant see, and the one you can see you can't fit a tool in to turn it. I would recommended buying a finger ratchet. Even after you get the screws out, it is difficult to unplug it because it is plugged in from the back with 3 different connections. I went ahead and unplugged all the wires to the Body Control Module as well because they seemed to be in the way. I don't know if you have too but it gave me some more room and confidence that I wasn't going to damage them. There is a short youtube video that gives you an idea on how to do it. Also, I got my part off amazon and it is the same as the stock.
So it's possible. Just very hard to do in my opinion. Good luck!
- 2010 GMC Acadia SLT with BOSE Sound.
I appreciate your comments. Can you call onstar to reset the car radio sound issue? I had a buick enclave with the same issue and got an amp and that didn't fix it either. I am a new owner of a 2012 GMC ACADIA SLT I really don't want to waste my money. 208-770-0049 if you can text to discuss. TIA 😊My wifes acadia started making this deafening sound anytime audio was supposed to play (turn signals, chimes, radio, etc.) I am replacing the amp today hopefully it solves the problem. I took out the old one yesterday and it is a pain to work with.
