I have a 700bt that I hooked up on a 08 Diesel motorhome and took out the stock Jensen radio that had a Sirius subscription that worked. I purchased the CD SB10 and thought the Jensen tuner/antenna would work with it. The imput that went into the old Jensen head unit fit nicely into the SB10, but even though the icon for Sirius is lit up, it keeps saying "no device". Do I need a universal tuner or should the Jensen work?
