That is the correct model # verified from a unit swapped out of an H2. When the unit boots up, does it have a Bose symbol, a chevy symbol, or the H2 symbol? I would tend to think that the nav you have is not going to work in the H2. You could try to have the dealer reprogram the unit, but I don't think it is able to control your amp (lux bose). The amp is under the center console. I am not sure if you can swap in the amp for the nav you have or not; I think the plugs are the same at the amp but might be a little different configuration at the head unit as far as wiring goes. Just send that nav back to the guy you bought it from (fleabay???) and get the correct one for your truck.
