I bought a sirius sportster r a few years back, it was from an electronic store that was closing, they said it had lifetime subscription. So its been sitting in a box for about a year, broke it out and it still works (after it went through 30 minutes of updating). So i have it hooked up through a car dock in my car right now but in the next few months im looking to buy a new car (kia optima) and want to figure out if there is a way to transfer the subscription to the aftermarket pioneer dvd player ill be installing. i would rather have it on there than have to have another ugly cradle dock in the brand new car.

Any input or info would greatly help.
Thank you
