I have for sale brand new never has been installed not locked radio CD player for H3 H3T. These are the exact radio that was installed in H3's with the UB0 code, GM part number 15852200. I picked up a few of these after the H3 was canceled. These are guarenteed to work. Selling these for $85.00 that includes shipping by USPS. PM me if interested.

 

XM radio?

 

All H3's radios were made to work with XM. There is a seperate XM module that hooks to the radio for it to work. If I understand you can buy GM or buy aftermarket XM receiver that hooks into the radio. If yours didn't come with XM the aftermarket would be better as your wire harness wouldn't have the hookups for the stock one.
