Ok, Thanks! What is the disc called, where can I get one and how much$$?? Cant stand the beeping sound every time I adjust the volume etc. Thanks for your help!

Ever since I unplugged from harness so I can figure out day/night display issues, which I was successful with, now cant get into Navi Menu to customize setting. When Navi Menu is pressed all I get is a message to "insert proper disc". Problem is the unit was already installed in my 08 corvette Z06, no disc included. Dont care about navigation working just want to reset some features in the Navi Menu.....HELP please.
