v.2012 sku#22846887

Does anyone know if I can finf one other then ordering through GM

 

Hello and Welcome to HF fellow H3T owner.

I would suggest Ebay or even craigslist for the Map Update.

I don't think it is worth the $. I tried the upgrade in 1 of ours and the other has the 2009 version. Well there was not any difference in the 2 versions. My wife has the new version is hers now. Mabye if you live in an area that had a lot of new roads and or road modifications in the past 3 years it may seem different.

 

This is particularly easy to bootleg/pirate a copy for a "Backup", especially since you have an updated disc in your household. Feel free to PM me about it tho.
