Many thanks for your reply.
It'd be much easier to get routes and navigation from the same source.
Meanwhile I'll have a look at CoRider.
The following mobile apps have been recommended by other users of the site:
iPhone - CoRider
Android - OSMAnd
We're hoping to introduce our own app at some point but don't have anything at present, although you can still monitor your position on route maps with the existing mobile version of plotaroute.com (by touching the tracker icon on the bottom right corner of the map).
Hope that helps.
I am totally new on this forum so maybe this question has been asked millions of time already..
However, can anybody suggest me a good app (iphone) to upload gpx flies in?
I am riding a road bike but at the moment I do not think is worthwhile to invest money on a Garmin edge device considering the mileage I do a year.
