Whichever radar detector you choose, whether Escort, V1, Radenso, Uniden, or other, I highly recommend installation using mirrortap and blendmount products. Mirrortap (or similar knock-off) will be for simple powerering of your device right off the switchable power from the overhead console wiring harness. Blendmount is a clean reversible mounting solution that clamps onto the base of the rearview mirror assembly without having to use adhesives or suction cups on the windshield glass.
I mounted and powered my dashcam this way and love the results. Radar detectors are mounted the same way. Only thing better will be a custom hidden install, but this way is clean and simple to do yourself.
