Well that wasn't easy; I've just spent several hours getting tomorrow's audax route onto the unit. For some reason it would only accept two of the legs initially and it took me a while to get the other legs loaded. I'm sure it was much easier on the original.
I shall have a map with me tomorrow as well.......
On a more positive note, the Garmin worked OK on today's ride although the built-in mapping only thinks there is one road in Cheshire.
More news; Evans have found my map card.
