Auctionking

First time Lexus owner , First time poster.... Has anyone had trouble getting the XM radio to activate after the free trial is over? I purchased this 2010 used and the trial had expired. After 3 weeks and umpteen number of refreshes it just wont activate properly. I have listened to so many hours of the preview channel while waiting I can almost repeat it from memory. XM has given up and told me to take it back to the dealer. I can't see it being a hardware issue when the preview and weather channels work perfectly. 5k on it in 3 weeks and it is a dream to drive. Thx in advance AK
