I'm brand new to the forum and the Hummer world. I recently purchased an 05' SUT that I really enjoy. However, my vehicle did not come with the navigation disc. My question is will the other years H2 navigation discs work that I see for $50 on ebay or do I have to buy the newest $300 disc that says it works with my navigation system. Thanks for any help or advise.

 

I just bought My 06 H2 and I have 2004 map disc the previous owner bougth the disc on ebay for 100 $ now it works but Ican't put any addresses so I had to get another from gm for 250 $ canadian Ithink go with gm disc at least you know its garranted
good luck
