Most of the time I use nothing but there are occasional times when I need to use the phone since I am now semi-retired and have a driving business. I prefer using my Garmin for navigation assistance because of the larger and more legible maps and clear verbal directions. I have a magnetic Scosche mount specifically for my phone that I have attached to the closest vent grill so I can minimize any distraction. Works pretty well. I suggest using the verbal option to direct you so you can keep two hands on the wheel. Google maps or Waze can do that.

Whatever you buy, don't skimp on the mount. You want something as secure as possible...:)
