Customer Question
I have a 2008...

I have a 2008 Avalanche LTZ and my Navigation periodically indicates the disk is not a map disk, or if it is working the destination button has a problem allowing the selection of a city after selecting the correct zone.

Mechanic's Assistant: Are you fixing your Avalanche yourself? What have you tried so far?

Ordered and installed a new update disk ver 6.0

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Everything else works great

Hey how are you,I will try to help you with this issue

I would start by scanning it using GM Tech II for faults and if none found ,updated the nav system using the GM II scanner with latest version should solve that problem

will cost you around $180 at dealer ,some shops if they have the scanner to do it might be a little cheaper ,some people try getting updated cd from ebay ,some work some don't key, here to make sure it is not the nav unit itself then move to software update will be my advice so you are not guessing and throwing parts at it

You are very welcome :)
