Most modern cars have a security code enable for the installed radio/cd players. This is an anti-theft device.
The initial documents given to the owner when the vehicle was purchased lists this code and how to reset it.
If you are second owner/original owner who has lost this information, then, you can approach gmc canyon dealer and they will have this code on their server. Normally a free service (I believe).
The security code is lost from the radio whenever keep alive voltage is removed from the radio. i.e. You disconnected or replace the battery.
Park the Canyon on a flat stretch of road or driveway and open the hood.

Jack the car up in the air and get it safely on jackstands.Then remove the front tires.Remove the calipers and caliper mounts.Then remove the center bearing cap, next remove the bearing tension nut, then the outer bearing will fall out with the washer.Last step is to firmly tug on the rotorand then remove the bolts in the center part of the rotor to split it from the hub.
1st try to hit the eject button multiple times in a row. If this doesn't work you have 3 options.
1= pull the radio unit, disassemble case, gingerly remove CD, and reassemble.
2=Go to dealer or repair shop and have them remove. If you have a warranty left, mopar should be able to help. Factory radios have been a problem with Mopar for years.
3= Go buy a new CD and forget about it
you have to start by removing the trim around the radio. it just pulls towards you then unplug connector (if any). Remove three 7 mm bolts from the radio mounts. Radio will just pull out. Not if you replacing it with aftermarket. there is now acc wire in the harness and the ignition switch is to weak to power this wire so the use of a GMRC01 from metra electronics will work perfect to supply you with all the connections needed for the aftermarket hookup
