Question about Passport 8500 Radar Detector
Started geting service required message
Service Required means that your 8500 has repeatedly failed while attempting to calibrate its radar antenna. This can be fixed by Escort for free if your RD still is in warranty. There is a service fee if your RD is out of warranty, but at least Escort will fully test everything in addition to repairing your 8500, and they will upgrade your 8500's firmware to whatever their latest and greatest firmware is which may help to improve sensitivity, reduce false alerts, or to detect newer laser gun models.

For 'Service Required', cooling off the unit only may not work. You may need to 'Rest' the unit. You need to hold all three buttons down on the unit and then plug it in. Once it goes through its bootup sequence, you can let the buttons go. Remember, this will reset any settings you previously had and you will need to redo them.

I had the same problem take out the 3 screws on the bottom, take the unit apart , the metal horn type thing is the antenna, take out the 4 screws the antenna comes apart you will see a circuit board clean with rubbing alcohol , clean the other circuit boards , put the unit back together and it should work fine, mine did and has been working fine for about 3 months now, without one service required message

My problem always happens when i turn the unit on, not while already riding/driving out of the blue
i believe the problem might be from the unit getting hot from being in a car, or on a motorcycle, or in a jacket in the hot sun then powering it up while still very hot, some kind of overheat circuit
find a way to cool it off, ride a short distance with it turned off then turn it on or...
also take the 8500 in you right hand and tap it in you left hand 3-5 times, it should start up and be fine. this doesn't have anything to do with temperature but i've had luck with it
