the good news is, you are not jeopardizing anything. the only bad can happen, is dealer will tell you they can't do it. I was working at Hummer stealership when first H3's arrived. I had to do many radio reprogrammings, never really had any problems to reprogramm the radio.
all GM radios (exept navigation radios) are compatible with premium or non premium audio systems. during the calibration, technitian will have to make selections on (TIS) what your vehicle has (bose or monsoon or nothing), and that's how the radio and BCM knows what's happening and what to do.
there are 2 ways of doing reprogramming
1.
Remote. collecting info from you vehicle to the Tech2 and then do adjustments on the computer. then connecting Tech2 back to you vehicle and upload new data. this method does not always work.
2.
Pass Through connecting your vehicle directly to the computer. most effective way to do it
3. sometimes no metter what you do or how you do it (technitians I mean) sofware keep giving you errors. and that's when dealer tell you that they can do it and still charge you money. However, if they were not lazy, they could call their their tech support department. and ask for VCI number. that number will be inserted into reprogramming software and then no more errors.
I sold many H3 radios on eBay my self, never had any problems with buyers not be able to have that radio reprogrammed.
So I think you'll be fine
