We have had a Simrad VHF with the wireless remote for over a decade. It just works, as the saying goes.
I installed the "snap in" charging mount by our nav desk, and the handheld device is always ready to go outside for use. One caveat - applies to many many devices parked on the cupholder bracket in front of the wheel, is that if you are about to use/rely on your magnetic compass for information be Sure to remove the radio handset with its little speaker. But you knew that already.
We like the way it instantly communicate with our Lowrance Plotter/Radar with AIS (receive) info, as well.
Reliable tech, so far, at least.
