Phone or Sat Nav? What mount ? Quad lock or......

[SportsterDoc]

My phone is holstered on my belt.
If I need to check a map (as if getting lost is a bad thing...unless fuel is low), I pull over and check.
Not a common occurrence, as I plan routes in advance, especially fuel and food stops in remote areas.
If the route is complicated, sometimes I jot down steps on a 3x5 card.
If I decide to reference the card, a quick stop offers a chance to stretch and sip water.

I've thought about a GPS or phone holder, but riding in high temps is a concern for electronics.

I did use a GPS (suction cupped behind windscreen) on my 1105 mile 6 day ride Sep 2020, but then gave it to a granddaughter, as I really did not feel the need to continue to use it.
