Bevo,

Do NOT buy part number 15120706 for your 2003 H2. That part number is for the 2005 (and possibly late 2004) H2s. I am working on this now.

The Bose amps were changed in mid 2004 to a lower grade model. 2003s have the "LUX" amp, just like the Cadillac Escalades. The later 2004s and the 2005s have the "premium" Bose system. You can tell the difference my the audio selections available on your radio. If your audio selections include "Normal, Driver, Rear, and Spacious" you have the "LUX" amp. If your selections include "Custom" you have the "premium" amp.

This is important, as the 2005 Hummer has the "premium" amp. The TNR for the "premium" amp vehicles appears to be different than for the "LUX" amp vehicles. Picking the wrong combination appears to not work (no audio).

The 2005 Escalade appears to have the TNR and "LUX" amp combination.
