My wife has had a problem forever with her 8200, where it freezes when she uses carplay. I got the w8500 for the wireless, thinking it would resolve the freezing. It didn't. She has to turn the car off to reset it each time, and has no stereo until she does so.

I would like to install a toggle switch in her glove compartment so she can kill the power to the stereo while driving, then power it back on. Will it hurt the stereo to only toggle the constant? Do I need to also toggle the accessory power wire? Will the stereo even turn off if the constant is turned off but accessory is still on?

Thanks!
