Hi,
I live in the Pocono mountains, I switched to an Onyx plus radio and it cuts out alot more than my old radio. The bars are going up and down all the time. I am going to put my wifes old Sportster 5 in my car. My questions are, are there different satelites for XM and Sirius? Does the Onyx Plus use XM? Does the Sportster 5 use Sirius? And has anyone else noticed more cutting out than before?
