I have a Terk XMDGMK XM adaptor on my OEM radio. XM was working fine before the vehicle sat for several months (battery tender attached). When I last used it the XM radio would only show "XM Loading" and would never connect. AM and FM are fine. I've researched solutions and it seems disconnecting the power to the radio is one suggestion. Is there anything I need to do other than pulling fuse #41 and letting it sit for a few minutes? Anyone else have this problem?
