Jay got me an XM Skyfi2 receiver for Christmas and also the mobile mounting kit. As it was Winter in Minnesota and the garage is not heated, I put off installing the mobile kit until Spring. This Spring I eventually got it all set up and it worked fairly well. It did everything it was supposed to, with one annoying glitch.
Every once in a while, it would forget its settings. I'd start the car and the XM set would not turn on. When I turned it on, it was like it had just been authorized but not yet programmed. I tried to diagnose just when this amnesia would occur, just in case it was something within my control, but no pattern emerged.
I'd had enough of this. I read the warranty and had Jay call about the problem as the warranty required the purchaser be the one to make a claim. Three phone calls later he had a ticket number and a return authorized. We packed up the Skyfi2 today and it'll be mailed off Monday. In a couple weeks the replacement should arrive and hopefully I can program it once and be done.
I've gotten very used to having XM in the car, so I know I'll miss it. But I still have the AM-FM broadcast reciever, the mp3 player, and the tape deck, so I'm not exactly hurting for audio options.
