2008 Hummer H2 Navigation GPS Location
I am upgrading a Hummer 2008 standard radio to the OEM navigation system, and I need to install the Antenna Assembly - GM (25918632). I have searched and searched... does anyone know where this mounts to? I cannot find the OEM mounting position. Thanks!

Right... I am pretty sure that is where it is located on the H3... so I checked that location, and I can see the airbag, and then the mounting brackets for the grab bar above them... but I don't see a plate to mount the square GPS antenna. Maybe the mount is not provided with the UVA option, and only on the UVB option? I searched to the left of the radio opening, and don't see much. In the center top is where the dash speaker is mounted. to the top left, I don't see much. Then provided a photo behind the dash front-right, and all I see is the airbag at center and them mounts for the grab bar above.

This might help - drawings and part lists. You will need to pick the correct one though. I do know that first one shown on the passenger side roof with a small mast is an 03/04 only thing - those had the AM/FM antenna on the roof instead of the fender. Check the below link.

@MixManSC - thanks so much... they had the diagram... it mounts under the Upper Dash Panel in front of the Driver. Makes sense so that it has a clear view through the windscreen. Here is the big question. My Upper Dash Panel, like most, has small cracks in it... and I am super hesitant to pull it out as that part is impossible to find a replacement for. It also has a ton of clips. Anyone have some advice on how to get the Upper Dash Panel out without cracking it? Is it even possible? Worst case I could just stick the antenna in an open spot under the dash and hope for reception... as I will really never actually use the navigation... just want to have the stock functionality in the H2. @HellHoof - had mentioned in another thread that he had reached out to Dorman to see if they would start manufacturing replacements, but not sure if they ever started. His photo of a completely cracked panel that he tried to remove from his Avalanche scared the Cr*p out of me!
Thoughts?

I had a New OEM NAV Radio installed and programed at the the dealer. They also replaced the NAV Antenna also. Not sure but I think you can get it in there without pulling the top dash, Mine is a 2009 SUV H2. On a side note. Be careful when unplugging that Antenna from the Radio. It's kind of a Funky connector.
