I just thought I would provide this information to those who have purchased a used 2007 with factory nav. I found this information surprising and you may too!

I called gmnav today and inquired about upgrading my nav disk from v1.10. They informed me that the original owner had not taken advantage of either of their 2 upgrades and that I could take advantage of this at no charge. I now have a new nav disk on the way.

I have my old nav disk V1.10 out of my 2007 tahoe I can sell. I only have the disk, nothing else. Shoot me some offers otherwise I will sell it in an auction!

 

hey big...sorry for the hijack, but how can I determine the current version?
I have my dvd case, it hasa part number of 15934919. but I dont see anythingrelating toversion.
Thanks...

 

Mine has the version on the disk, ex: v1.10. HOwever, the disk you have is a v2.0 I think.

 

How do I get in touch with gmnav to order my new disc?

Thanks!

 

I believe the website is gmnavdisk.com or gmnavdisc.com. You might google it.
