I've just gone to load up my courses for a 7 day epic and I can't get them all on my Edge 305.

Does the 705 have more capacity or is there a way to free up more space on the 305?

I have 5 days of rides on there before but even those same ones won't fit now.

have you went through and deleted off the courses and routes already on there?

with the 705 you have an external card so capacity is expandable, not sure about the 305 but I don't 'think' it's got the same slot, ie. you're limited to the spare space on the main drive.

(on my 705 I've got about 30 routes and coming on 6500 miles of historic data)
