When we purchase our current RV it came with a free 6 month subscription to Sirius. A few months after that we bought a new tow vehicle that came with a free 12 month subscription to XM. By the time the 12 months was up Sirius and XM had merged. Called them about combining accounts and was told they could not do it. Threatened to cancel the XM account and they gave me the multi-receiver discount of 30%. The next year I had to go through the same process by threatening to cancel before they were willing to negotiate. Finally this year they were able to combine both accounts into one. I refuse to allow them to automatically renew which costs me an extra $3 per year for them to "invoice" me. Its a small price to pay to allow me to keep control of when and at what price they renew my service. Next year I may try the "lifetime" subscription if they are reasonable. Love the service and hardly ever listen to regular radio any more.
