No problems at all. The display is easy to read, with large, bold lettering. Where it is keeps it out of the sun, most times, and you do get used to the controls so you don't need to look at it all the time.
It may have been better higher up, perhaps eye-level, but then you have to drill for the wires, and it would stick from the dash a bit too much. Another place I thought of was up near the rear view mirror..............
