2021 Yukon Denali

[Steveo22]

Hello, I recently purchased a certified pre owned 2021 yukon denali and have a few questions.

In the instrument panel there is a small white sign that should show the posted speed limit. Mine just is blank. I have checked the box in the settings menu but still not working. What am I doing wrong?

Also what start stop harness should I buy to eliminate the start stop function without causing any other problems.
Thanks

Full transparency. I'm not conversant on your model year.

Regarding your blank speed limit icon, my guess is that your truck is not receiving GPS information. I 'think' that is typically supplied by OnStar. Do you have an active subscription to OnStar?

I had to buy a subscription to OnStar to receive posted speed limits on my screen. The Dealers use to give a trial offer to OnStar with all the goodies. Maybe check with them or OnStar may offer the trial as well.
