My 997 satnav is out of date, and I find the smartphone mapping works better. I've got a Samsung Galaxy S5 but all smartphones are fairly similar in size. The problem is mounting it in the car. Windscreen suction is too big and clumsy, air vent mount is not secure and points a little downwards, and the cup holder mounts look a bit high for a 911. Has anyone found a good way to mount a smartphone easily and securely?
