Hey, I feel the pain. I also have a 536 that had to be religated to a remote feed because I have no other use for it.
The problem is Uniden keeps saying "it's coming", so its not false advertising. If they come out and say it cant be done, then it would be false advertising. See my point?
Lawsuits do little to get the reaction you want. A couple thousand calls to headquarters would certainly get their attention. A sudden 50% drop in scanner sales would get their attention. A lawsuit wont, they'll just pass it off to the corporate lawyers.
