I had an Edge E-Z installed on my LB7 in early July and after having three total shutdowns while driving down the road in 10 days I decided it was time to return it. The responce from Edge was they had no knowledge of this problem ( I knew different after reading some similar occurances in the 911 section). I have been using my new Edge for about six weeks and have had no more problems. The old Edge was a Ver 3.xx and the new one is a Ver 10.xx. That is seven major program changes and who knows how many minor ones. Anyway this one works, so I;m a happy camper.
