After doing a ton of reading on the subject and trying to figure out what the heck's going on with all this stuff, I have come, most importantly to the conclusion that a
Y91 code on a midyear 04 and up H2 does not indicate the same thing as it does on most other GM trucks including earlier H2s. This should have been obvious to me, but I made the mistake of employing logic and thinking the General would assign a different option code for a different radio system.
But apparently all Y91 means is that a unit has the top of the line stereo system offered that year, which could be Premium or Lux. So don't use that as an indicator.
However, after coming this forum and the Avalanche forum for threads, I decided to get a Lux amp to go with my Lux head unit. I understand that Lux amps are programmed to optimize the sound for their particular vehicle. Now as far as I know, there are no SUTs that ever came from the factory with a Lux amp, so there is no vehicle specific programming for my truck. But I went ahead and bought an Escalade LUX amp anyway (p/n 15060881) to see if it works and how it sounds. I don't know if this has ever been tried, but I'm going to be a guineau pig.
I bought my Lux INR off ebay for $504 and the Lux amp off ebay for $133.59, so I'm not terribly invested in the project in any event. I could probably resell the parts on ebay and get the Premium stuff if this doesn't work, but I want to give it a shot.
I know I'm going to have to move some wires in the amp harness to make it work with the Lux amp. I found this page
http://duramax.onlinedesk.net/navinstall/ that has a pretty good description. If anyone has any further input or suggestions, I'm all ears.
