For the Sirius part, it makes no sense to me. I would expect the Sirius ESID to be the same since it is normally an external tuner.

You get a free year to Sirius with a new BMW. It does have to be activated and Sirius sends you a welcome packet on activation. So -- the first step it to see if the ESID changed.

If it did change, Sirius should be willing to roll over the remaining time on your original free subscription to the new radio.

Note that I use the Sirius website to do most stuff, it will show the ESID and subscriptions you have.

You may want to scan and post your receipt from the service. That will help folks to understand what they did.
