New owner, couple questions and issues

Just picked up a 22 Yukon Denali about a month ago but my Onstar/Navigation isn't working tried to call onstar they couldn't activate. Could It be an update or a problem with my onstar module?

Questions-
1) Does anyone have a catch can or range technology AFM/DOD delete (Plugged inline with PCM) Should I bother getting anything or ride out the warranty? I don't want to void it with either of this.
2) Previous owner started to blackout the truck, they did the grill. I'm looking to get the bottom valance and fog lights in black - do I need to remove bumper to swap those pieces out?
3) Best cold air intake


thanks

Welcome to the forum!

I've asked a similar question here just recently about the lower J-shaped foglight surrounds. I don't have a definitive answer yet, but it appears that you can remove those and the bottom/center piece from the front of the truck. It's just that I want to remove mine without breaking the tabs -- and I'm not sure how to do that yet. When I get the black trim pieces in-hand, I'll have a better idea where the tabs are.

Check the Engine/Performance and General forums for info on the AFM module that was just released in the past few weeks. Also, a few folks has added a catch-can. You'll find posts on that here.

It sounds like you might need a software update if your nav/onstar isn't working. That, or the headhunt needs replacing. There are posts about that here, too. (Try the Electronics section.)

Not sure about your mirror issues -- but I'm sure someone here will be able to help.

In the meantime, post pics of your truck!

I would suggest performing a full reset on the Radio, then trying to get OnStar Activated...

You can reset by Going to System --> Reset Options.

Hey I think I did that, it restored it back to factory settings. No blue light lit on overhead console

I think there may have been some cases of people having the OnStar Module Die, quick search revealed this thread:


Also, a few others on reddit, etc. If not working, head to the dealer. If you are still under 36k miles, will be warranty.
You might also have some warranty from the dealer on a used vehicle (In MN is like 30 or 60d)
