I have a passport 8500x50, the windshield mount broke, i've opened it and used electrical tape to secure the mount back onto the top inside part of the radar and am now unsure if this has caused the radar to be less sensitive than usual. Everything seems to be functioning fine, but i would rather not risk it.
The same has happened to me. Instead of monkeying with it i got two pieces of velcro. Put one on the top of the dashboard and the other on the bottom of the radar. Dashboards are usually highest over the instrument cluster so I mounted mine just to the right of that giving me a good height like when on the windshield, its out of your way, and still near the cig lighter. Mine works great in that position, I have not noticed any difference in function and it still saves me. ha!

The unit comes with a windshield mount - assemble the bracket ( if needed) and secure to a location on the windshield. Make sure its above the wipers and not behind any metal. Once installed, make sure that the radar detector is LEVEL WITH THE ROAD! This may require bending the bracket to level the unit. (Note: remove detector while adjusting the bracket).
I just had this same problem. It's an easy fix. The "washers" that fell out aren't washers, they're the reason that the button fell into the unit. They are plastic "rivet heads" from the way the frame of the button is melted onto the cover. You can throw them away. I used super glue to re-attach the button to the cover.
This is fixable as described in other threads here. This is annoying and seems to be random, though it also does it sometimes when the wipers are turned on or I use the windshield sprayer. 2 minutes with a smal Philips screw driver and a Q-tip will fix it. I just did mine and it works great now.
Unscrew the three screws, pop the three components apart (it really is a no-brainer since they only fit back together ONE WAY, so don't be nervous. There is not anything that is going to fall apart or spring into a hundred pieces in there.
I used canned air to blow everything out and just used the Q-tip on the front window and the parts that looked like the detector window internally... I didn't bother swabbing all of the board.
IT WORKS! GREAT FIX!!!!! DO IT!! NO MORE FALSE LASER ALARM WHILE ACCELERATING and randomly.
Does this happen in the city or does it happen when you are out in the middle
of nowhere? I have seen laser detectors that are falsely triggered by various
lighting devices that contain wavelengths of light similar to those used in
If this is annoying and you dont want to hear it, you can locate the receiver
element that detects the laser signal and cover it up with a piece of black
electrical tape. That should stop whatever is causing your problem unless there
is something actually broken inside the unit.
First you should try it in another car if possible. It sounds like an electrical problem. You need to rule out if its the car or the radar detector.
Open the end of the power cord it unscrews, check the fuse in it to see if its blown.
Ive also seen the screws loose that hold the circuit board down cause problems. If its out of warranty now, there should be a screw on the bottom usually under a sticker. If you peel that back and remove the screw, and lift the bottom off..Tighten any screw you see holding tbe board down, dont tighten it to hard. Then replace the cover.
Post back after you try some of those, let me know if it still does it.
