I have a subscription to Sirius and it is far superior to XM. Does anyone know if it is possible to switch from the in dash XM to in dash Sirius?

 

I do not believe tat this is possible. I have a seperate Sirius Tuner also in my RL but after comparison I prefer XM. The sirius is going away once the pre-paid period is completed.

 

Could you tell me how you put a separate Sirius tuner in your RL? Was it professionally done and do you get good reception? Did you have to disconnect your XM tuner while Sirius was installed and working or could you switch back and forth and listen to both? I would like to have Sirius in my 05 RL now.

 

I'm pretty sure it's an FM modulator set up. That's what I had in my TL.

The sound was great, but you lose the ability to leverage the audio controls on the steering wheel (Channel up/down). You end up using a seperate remote.
