I used Passport Escort 8500 in all my vehicles for YEARS and they were great, until modern cars started using K band radar for lane departure systems, automated cruise control, etc. Now they beep non stop with no way to update them.
I've started replacing them with Uniden R3 detectors that have advanced filtering, the ability to be updated via internet, and several other features that eliminate false alerts. Put one in the Camaro to test for a month and liked it enough that I bought a second one for the Hellcat. Mounted to the mirror with a Blendmount and get power from the rearview mirror with a homemade wire tap. Reasonably priced at about $300 to boot.

Wire Tap: https://amzn.to/2Slh8RN - but you can make your own from an old phone cord if you're clever
