Query: Enjoy it while it lasts

I have owned two of these units, both brand new. The first one lasted about 2 years and then started overheating. So I chalked it up to overuse an bought a second one. This one was working fine for about a year and then stopped acquiring the satellite signal. No bars. The ID screen is blank. Like it forgot who it was.Is there a way to reset these things or re-enter the ID?Buyer beware. These units are a waste of money. And to add insult to injury, Sirius charges you to move the service to a replacement unit.
