What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[j91z28d1]

you can sync the rear to the front or turn it off but no lockout like there used to be on the 800's

ugh that's kinda annoying. little fingers and toes like buttons haha.

You can take it apart and stick some paper behind the buttons.
I used some scotch tape folded onto itself for the rear radio controls..

I see why you got rid of the auto hvac. overall I miss simple ac with rear ac controls.

You know what else is annoying?

There is no rear-speaker mute option, for example, if kids are sleeping in the back and adults want to continue listening to old-people music.

Figured out why my 02 sensors were not setting....
I thought I had a older BB tune installed but it turns out I had a later one with the 02 sensors disabled, reset everything and put a 2019 tune on it, drove it around a bit today and walla 02 sensors are set I know the rest is good so, duh

Yeah, it is a little annoying having to go into the settings and change the bias to the front speakers only, and it doesn't sound as good either.

Bose, in general.

After 55 years of wanting and waiting for a forced injection vehicle, I finally bit the bullet and installed a Whipple 2.3L supercharger on my 2007 Yukon XL Denali. I'm looking forward to some fun times in the near future.

well I requested some changes this past summer and they sent me 2-3 different tunes and I mistakenly thought I had put the original back on it but after digging around I found it was really from july/24, how I screwed that up I don't know and how I didn't find the 2021 one on my computer until several tries I also don't know I searched 4 hard drives because I normally backup everything and still only have 1 copy so going to back it up now......
