I received my new (refurb) 8500 X50 today and immediately took it out to compare it against my 9500ix. I went to know location (Lowe's) that had a strong K band door opener and compared the two detectors (not running at the same time).
The X50 appeared to have the same range and sensitivity to the ix and I was very pleased. It seems to be very strong on detection.
On my return trip, I made a stop. When I got back in the vehicle and started it, my 8500 came on, with the direct cord hard wire, but went straight to self cal. I turned it off and then back on it appeared to reset with no problem.
Should I be concerned and or should I do a hard reset? This is my second refurb and I really want this thing to work. I obviously have time to run with it for a couple of weeks, but I am concerned.
I have posted this question on the Escort Forum and would appreciate any input.
