I have been having a lot of trouble with the factory installed Sirius radio in my XJ8L. The scroll buttons in the channel list are grayed out and don't work. The Sirius will sometimes cut out and stay off for 2-3 minutes. Sometimes it will not come on at all and I have to stop the car and restart it to get the Sirius to work. I have brought it to the dealer 5 or 6 times. They have replaced the Sirius module, antenna, harness and tried a different radio head. Nothing fixed it. Now they say it is operating "as-designed". It seems like a software problem to me, but they say it has the latest software. Does anyone have an idea what to do?
