I have an 07' Denali w/ XM and I would like to switch it over to Sirius. Can I do this without changing the stock stereo or adding a seperate unit? Also, in my 03' F250 I have a Sirius plug and play radio that works through the radio. This sucks because it will get fuzzy and your always trying to find stations that will come in. Is there a way to avoid doing this?
Thanks,
Mike
