XM to Sirius conversion?

[MKEELINE]

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

This is what you need for the Denali http://www.tss-radio.com/sirius-connect-sirgm1-p-228.html and this is what you need for the F250 http://www.tss-radio.com/direct-adapter-wired-relay-p-4082.html

Thanks alot. Will the FM direct adapter(F250) eliminate the need to run the Sirius through an FM station?

It still goes through a FM station only it's a direct connect to the radio rather than that peice of crap antenna they give you. The problem is they had to turn down the transmitting signal on all of there radios about year ago.

this one won't work for the newer 07 tahoe, one is releasing at CES in january for the 07 LAN based cars/trucks. True on the fm transmitter, it wasn't FCC legal and somebody complained about hearing howard stern on their fm and they didn't want to hear it. that's why my wifes car still has the s50 with the older stronger FM transmitter.
