Zumo 660 replacement

[Kenzogs]

I presently use a Zumo 660 but am becoming a bit frustrated with the poor screen definition - specially in bright light. I use it mainly to follow Off-Track routes that I have planned in Google Earth so do not often use it's other navigational functions.

What is recommended as a suitable replacement that will have good screen definition?
