I'm planning on going to a semi-permanent mount situation in my Fusion.
I've been using my Galaxy S3 phone in my car, with the Torque Pro app, and my ELM27 BT adapter for some time now, without an actual mount - just sitting it in the coin drawer as I drive, with moderate success. It works okay, but if I take a turn with any speed, the phone falls out.
Now that I have a new phone - Galaxy S7 Edge, which I LOVE - I'm planning on wiping the S3 of as much as possible, and using it as a dedicated Torque Pro/Fuel Monitor/My CarFax computer. To that end, I've been looking at numerous mounts for the car. Once I have one picked out, I plan to keep the S3 mounted in it while I'm driving in the car.
I say 'semi-permanent' because theft is always a possibility, and leaving the phone mounted visibly in the car when I'm not around it is just asking for someone to break in and steal it.
These are the mounts I've been considering going with:
WizGear Universal Stick On Dashboard Magnetic Car Mount
WizGear Universal Air Vent Magnetic Car Mount
Now I HAVE been also considering a more permanent mount situation, but if I do that, it's going to have to be something of a custom job, where I can literally mount the phone IN the dash. This will, of course, require some custom fabrication, and I'm not sure that I'm quite ready to commit to that.
