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
