I like that mount. I have my Escort Max360C hardwired much like yours. However, I have the suction cup that will occasionally fall down during high/low temp combinations.Mounted my new Escort Maxcam 360c and also hardwired it to the rear view mirror.

The only reason why I did it this way is because this radar has the mute button right at the front so it's pretty convenient to mute it. Otherwise, I would have left the smart chord on.I would love to mount mine here, but I can’t live without the mute button on the charging cord.
