Apologies if this has already been covered but I have searched!
BaseCamp 3.1.2 accepts GB Discoverer maps and track and waypoint data from my Colorado 300 with no problems. However, all the 'New' options are greyed out making it impossible to create a new route, waypoint etc.
From reading others posts, I know that this is possible but no matter what I try I fail miserably.
Advice, please.
TIA.
