I bought a sportster 4 radio and the universal boombox to use in my office. For the first month it worked fine. Then my radio would say Low battery warning and shut off. My boombox seems to stay powered on, as the green light stays on, but I can not keep the radio turned on for more than 5 seconds without getting the low batter indicator and it shutting off. I have it plugged in and sirius has sent me a new boombox but I"m getting the same thing again. I'm wondering if anybody else has had this problem and how they solved it, or if you know of a way to solve it.

I'm having the same problem Wingfoot. Driving me crazy!!! I hope you (we) get an answer from someone!
