, I am actually replying to how this was rectified. Unfortunately no one else on this thread seems to have solved their problem OR are not willing to share it.
All pricing is Canadian Dollars
You can follow the dismantlement on Youtube Not my car but the same thing
It will give you a good idea on how to start out. The rest is fairly simple.
At any rate, I bought the body tools to help dismantle the centre console st CDN Tire for $34.50.
Dismantled the console. The tools helped as the first two panels to remove must be pulled back, to the rear, and not just popped out.
The rest is just being careful to get all the bolts and unsnap the wire connectors. The big connector on the radio must be unsnapped, lever pulled back and then pulled out.
Next sourced "used" radio from scrap yard. Very important to have the part number and code from your original radio, on the top of it, as this will enable you to get one that matches. The one I got was from a Buick Verano. As soon as i plugged it in the screen came back on but indicated the anti-theft program was activated. Cost for the radio was $379.42.
Now off to the GM garage to program the radio to my vehicle and options. Took all of 15 minutes for a cost of $25.28.
So total cost was just under $450cdn and i get to keep the tools. A lot less expensive than the close to $1,500 that the garage had quoted me to change it out.
OH! The scrap yard warrants the radio for one year. Same as if I had bought a refurbished one from GM.
