OK, weirdly enough I'm replying to my own thread. I still am looking for details of the Nav antenna mounting however, I did discover some other stuff.
The ebay auction I bought my non-touchscreen nav off of specified that it was for any truck that had the Y91 option code. Well my 05 SUT had the Y91 option code, but unfortunately when I plugged it in, all I got was a buzzing sound with very low audio behind it.
So after consulting this document

I found out that the radio I had was
Newest Revision LUX INR--------15204335
Which obviously won't work with the Premium amp in my H2. However according to the above link the Lux system is way better than the Premium system and the speakers are the same between the two. So basically if I get a Lux amp, my entire system will be upgraded. In theory. But I screw this **** up all the time.
So I'm going to buy a Lux amp and try this out. I'll report back and let you know if it works.
The only other issue that I see with this is that there is a brace under the dash that the white nipple in the center of the back of the radio plugs into. On the stock radio, the wiring harnesses hook into the back of the radio on each side, but on the Lux INR radio, the wiring haness that is on the passenger side of the stocker (small connector) is actually right above the nipple and so it appears that it interferes with the brace that the nipple plugs into---I'm not totally positive of this, but it looks like that is the case.
Anyway, can someone please tell me where I need to bolt the antenna to. I found a thread with a diagram and the directions from the manual are not very clear. They actually may have been written by someone who speaks english as a second language. So if any native speakers could tell me how to mount the GPS antenna, I would appreciate it as this project has not gone very smoothly until now.
