I used to go to xm411.com but it looks like they are defunct. I found this site doing a Google search. OK, here is my problem. I've been an XM subscriber for about 11 years and the Delphi is the second radio I've owned. However, today it developed a problem. It was working fine in my car when I stopped at a store. When I went to leave, it would not power up; it would start to, get as far as the XM2GO splash screen then everything went blank. A couple of hours later it started working again, but it had dumped all my presets. OK, I reprogrammed 2 of them and started driving, but about 15-20 minutes later it died again with the same symptoms. So I have some questions: 1. Does anyone have an idea as to what is wrong with it? If so, where can I get it fixed? 2. If it is unrepairable, I'll need suggestions on a replacement and I assume replacement accessories. This is what I'll need: 3 car kits, 1 home kit, an adapter for my 2005 VW Jetta OEM radio, and an adapter for my Pioneer radio in my Mazda Miata. 3. When XM & Sirius merged they said there would be "universal" or "dual-band" radios available so you could change between XM channels and Sirius channels without changing radios; where can I get one of these? 4. Last, what current radio has the same features as the Delphi MyFi radio?
