I bought this
Mount. The AccessPort is magnetized, so it's perfect. I don't have a picture unfortunately. I pinched the cable just past the vent for the driver window. There's a bunch of cable on the dash, but I don't mind. I have mounted it on the window just above the driver side round vent.
The downside of this mount: it's not very long (I expected it a bit longer) and is not very customizable. The holding plates rotates and tilts easily, but the base itself doesn't rotate. The suction on it is fucking incredible though! I placed it once, and never touched it again. I installed it this last September and we got some small heat wave plus it gets very hot in the car under the sun and it never dropped and same so far this winter, we got some -30 and it's still holding like a champ.
The mount doubles for my phone too as my case is also magnetized. I'm thinking of buying another one for my girlfriend's car, but I'll have to pass that by her if she wants that in hers.
It's also super cheap compared to pretty much everything else out there.
