I bought this to replace a nav radio that was starting to act funny (sound would cut out for a second and when it came back it sounded like someone changed an eq setting, also cds played with some static) in a 2009 Avalanche with the Bose system.

I did discover that there is a "loudness" button in the amplifier that must be turned on for the sound to be good.

no good no sound, radio looks to be working just nothing

Great sound to boot

Sound is great and radio reception is as good or better than the stock radio.

The cons are heavy though, door ajarsounds like a submarine, turn signal sounds like the loudest clock I even put a sticker covering the sh!t speaker provided

The other thing that was a little surprising was that the sound was not great.

I have tried radio, CD, and BluTooth, the sound is fine, no issues at all

Sound “cracks” a bit when under heavy

My only complaint is the sounds of the blinker and door open warning sounds horrible

It fits perfect in my impala ss
