OK first off sorry if this is a DUP post but havent found any real answers so.....I have a new 07 H# that only came with the stock stereo single CD and im looking to see if the H# came with the option of a NAV unit. If so can i find this anyplace like ebay?...Been looking and cant find anything. Or would i have to buy from the dealer to have it installed?....Any help would be great...And once again sorry if a DUP post

 

I bought my FactoryNav for my 07 H3 Tactical on ebay and it works great. My only problem that I encountered was that Onstar and incar calling is very very very quiet.
