2010 Impala LT 3.5 100K miles with the Bose stereo, single CD, no Nav system. About 2 weeks ago I got in one morning and no audio from the system. No turn signal click, no chimes, no radio, no audio at all from any speakers, but everything else seemed to function visually, all LEDs in the display good, CD function good visually and mechanically, phone function good visually, steering wheel audio switching functions work, just no sound from any speakers for any function. Got back in the car after work and all normal function returned 100%. Now it has done it again. All of the above again. I did stop on my way to work and turned the car off, got out, let all lights go out, after a couple minutes got back in and started the car but it had no effect, no sound at all. I will definitely look into an aftermarket system later but right now (not to whine) I have a lot of unexpected money in the car and have to save up. Bought it about 8 mos. ago, decent deal, and transmission needed rebuild 6 mos. later and a few other repairs. Now I am way upside down on blue book value so I'm going to be driving it for some time, but all else is good on the car and I like it, even the stereo when it works. I have a bout 10 hours of driving ahead this weekend so it's a bummer right now. I'm going to try the fuses under the rear seat, check the connections on the amp under the rear deck (I think), disconnect the battery for a while. If nothing else I will buy a new/used factory head unit and amp. Which would you replace first? I would like to keep the stock functionality, steering wheel controls, remote start, phone, etc. if possible. Thanks for any ideas!

Fuses dont reset themselves.
Disconnecting the battery can lead to more problems .
You have a bad connection either external or internal to the radio system. Checking the connections would be a good place to start.

Hello again Zora and thanks again! This Chevy is driving me crazy as you might guess. I was not able to work on it last night and wont be able to over the weekend as I will be travelling. Looks like the cell phone and some earbuds for the trip, but we will see. Got back in the car after work yesterday and 100% function was back. Got in this morning and zero sound again. Grrrr. I am going to check the connections and next I think I will swap out the amp. Can get one for +-50.00 so wont be too painful. If I can get a matching head unit for cheap enough I will try that next. Thanks again.

So just FYI, still no sound when I was starting trip and I figured if the phone was to be my only audio source I needed to be able to charge it. Checked all 3 12V outlets in the car and NO POWER! First time I have needed power. So I figure maybe fuse blown and go to the manual, find the Aux fuse in fuse box in the passenger footwell (which happens to be next to the Amp fuse), pull the Aux fuse and it's good. But in the process I moved the Amp fuse and the dang audio came on! I moved it around a bit and the audio went in and out! Pushed it firmly in and the audio has been good ever since! Apparently a partially seated fuse or maybe the female terminal in the fuse box or the connector is slightly set back. Regardless it works again. The 12V issue I will deal with later....
Thanks again!
