Hi again,
I found switches on the back of the steering wheel. Spent a couple of hours going thru the manual and didn't find a reference to them. What do they do? If there's a reference to them somewhere give me a clue please.
Thanks.
Ron

 

Hey Ron, we just bit the bullet and got a 2020 Tahoe. Those switches for us are for the stereo system

 

I'll check that! Thanks!
Ron

 

Left Top = Next Track
Left Bottom = Previous Track or start song over
Right Top = Volume up
Right Bottom = Volume down
Note: Be careful with the volume it's context sensitive, if you hit it just as the nav voice in maps is happening it adjusts that vol., not the music.
