I picked up my HHR last week and it didn't have the XM radio I requested, the Chevy dealer said they will make good on it, they can't or won't swap out the radio and want to install an aftermarket XM radio, any suggestion on where to place it, there isn't much extra space.

I'm not sure if pro-fit makes any mounts yet for the HHR. But thats something I would use.

Hold out for the in-dash unit. It shouldn't be that much of a challenge for the service department to swap in an XM optioned system. I just prefer integrated units over component pieces in a car.
