This kit comes with two connectors: one for standard connector plates; shops like DX provide many well designed mounts for just a few bucks, much better than the original suction cup.
The other connector has a M6 hole for the vent clip I use in my Ford C-Max. Because it became too soft when heating too much, I made a hook like attachment which can stand more heat. It will still need replacement from time to time, if you live in a cold place.
