Bought a phone mount from cdslotmount.com a couple of months ago, and I find it's excellent. I opted for the deep holder, as my Moto G5 only just fitted into the standard holder, and I was afraid that it might fall out. The deep holder grips the phone firmly, but the rubberised claw does no damage to the phone's casing. The mount holds the phone nice and steady, and it's at a comfortable height to read the display easily. With my phone on the left hand ball joint, it doesn't interfere with any of the controls, and because it's a ball joint the phone can be positioned exactly as I wish. I find Google maps is very clear both audibly and visibly, but you do need to switch Bluetooth off in order to hear the spoken instructions. Hope this is helpful!
