I am currently using a Garmin Zumo 660.
I have a set of issues:
1) I want to store more than 20 routes on the unit
2) I want to use long names on routes and waypoints which I create
3) I want to be able to track my routes when I am on a long trip. E.g. 4 days x 500 km each day.
Can I solve this by buying extra memory ?
Is there a setting to expand names ( I believe the limit is apx 15 chars)
