Hi guys, I have been struggling to find a copy of this disc. I live in London, Ontario, Canada. I have spoken with the GM dealership and they can't get me a copy of the disc. Searched everywhere on the internet (ebay, kijijji, etc..) I am willing to pay for the copy, I have no problem with that, just please someone help me out. I got the caution incorrect disc mesage across the Nav screen after I replaced the battery.
