The TNR is a 2005 model, manufactured on 11/18/04, which I purchased new through GM. I had this installed on my 2003 H2, following the instructions posted on this site (they were perfect). As far a I know, you will need to have this reprogramed at a GM dealer for it to operate correctly. My version 3.0 dvd was new at the time, but is now 2 years old.
