I bought a new truck with Sirius/XM free for 3-months. What's the procedure for adding that radio to my XM account that has two radios now?
If it is XM you can simply call to have an additional radio added to your account for just a few more dollars a month. If it is Sirius then you will have to pay the full price as a standalone unit. Sirius and XM receivers are under two different billing accounts even though they are the same company.I believe it's an XM radio.
