GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi there, I am Cam. What base model is this? Denali does apply to trucks, Suv;s and such.
OK, you need to have the accessory switch assembly and heater head below it out. There are tabs that come up and engage the flange of the radio.
Oh just the radio itself, sorry I thought you were removing it. I have not torn down a radio nor is it in a GM manual I will opt out.
