I've had my LRD950 for over 4 years now and it's been a great detector for the most part. I've started having this issue where after about an hour of driving it will start saying "User Mark Logged" then "Delete All User Mark" and it will go back and forth doing those things until it freezes up maybe 10 seconds later. I've tried factory resetting the detector and updating the firmware and sub firmware with Uniden's utility and none of that has helped. Is my detector done for? It works just fine up until it starting doing this and I can't seem to find anyone else who has had this issue. Any information is greatly appreciated.
