hi Albert.. regarding the nav disc (part # 22846887) - saw a post where you had someone msg you for further details on how to obtain this.. any chance you can help me.. i tried burning a backup iso of this part # (since my original got *scratched*) to a verbatim dvd+r dl (set booktype to dvd-rom..) (didnt burn at slow speed though - i burned at max..).. when i insert into my 06 hummer h2 it just says check disc.. then when i hit nav it says "no map disc'.. any help appreciated! thanks

Hey man, former Army Ranger here! I saw a post you made about getting a copy of a map update.. I have a 2008 Hummer H3 and looking for an update to the stock Delphi unit but the discs are typically $200.. Any suggestions? Do you have a copy?
