Install Sirius SIR-GM1 tuner in 2003 Bonneville SSEI?
I would like to upgrade my factory system to have Sirius capability in my 2003 Bonneville SSEI. As far as I can tell, it is NOT wired for satellite from the factory. When I cycle using the BAND button, there'* only FM and AM bands. I assume that there would be an XM band if it had the factory XM option.
So if my vehicle is NOT wired for satellite from the factory, is it still possible to integrate the SIR-GM1 tuner?
Many thanks in advance!
