navigation system

[SteveGt]

I was looking at purchasing and oem factory navigation system for my 2004 h2 but was wondering if anybody can tell me how if it will fit or not. The ones I was looking at were for a hummer with y91 or y91 bose options I looked in my gove box and dont see any of these codes. Does this mean I should buy one that is for a hummer without y91 or y92? Is there any where else I can look? I just want to make sure before I buy it because I dont want to buy one that doesnt fit since I live in Canada and ill be purchasing from the states and I cant return it. Also ive called my dealer to ask and they were of no help to me. Thanks
