Question [Q] Navigation app for phone with half broken touchscreen

my Nexus 4 glass broke in half while in my pocket a few days ago. Insurance wont cover it and for the 155 I've been asked to replace it I'll buy a moto G.

Anyway, the screen works perfectly but only a half of the touchscreen works. I was thinking of converting it to a navigator to leave in the car. Do someone know of a navigation application which has all the controls on the top/bottom half of the screen?
