My "lifetime" deal with Sirius includes 4 transfers.  I'm only on my first radio.  I paid around 450.00 6 years ago.  The price was 12.00 per month at the time.  If I have to, I'll get a stand alone radio and use it in the new car instead of subscribing to XM if they don't transfer.  Thanks for everyone's help.
I just read the subscriber agreement on Siriusxm.com and it says that automotive receivers are not transferable in lifetime plans.  I was told at the time I subscribed that it was transferable to new vehicles.  This is a change and I wonder if my subscription is grandfathered.  If it's not, they can stick it.  All these new vehicles have mp3 hookups, so I can get all the music I want from our ipods.  I can do without the other programming.
