Ok, I'm positive i do NOT have a bose system in my '07 LS. But, i went to a stereo shop today to ask about having my double-din panasonic dvd player installed... when he turned on my car to listen to my stereo he said he was pretty sure it was a Bose system. I tried telling him it was a base model Tahoe. Anyway, how can you tell for sure? I'd imagine someone with the bose system would have bose emblems near the speakers or radio or something.

 

The speakers all say Bose on the grilles.

Check your sticker - it would say it there.

You could also pull out one of the speakers to check, but if the grille doesn't say Bose, it probally not Bose.

 

I do not believe your LS has bose. Do you have the center front seat console? Secondly, on the front A pillars is there a speaker cover in them that says bose??

 

No bose on the speaker grills and my window sticker just says am/fm radio, cd/mp3. I knew that it wasn't bose. I was just checking to make 100% sure that i don't have to get a new onstar wiring interface for bose. Thanks for the info... i'll pass it on to the stereo guy
