my solution!
put a ~ 3/4" strip of non slide black material (kind you use on boats and rv to keep stuff from sliding around) inside the lip of the cup holder. use very thin double sided scotch tape to attach the material, this way you will still be able to close the cup holder or use it.
now when driving rest the phone on the cup holder. since it is on the material, it will stay in place. the phone or google nav will lean against the clock but stay in place even on hard turns.
I had the $50 verizon mount but I like this better for when I am in the city because it is low profile.
sorry, no pics today.
