Etrex t35 : Route does not show map

[Idris-Dragon]

I created a "trek" route (On OS maps, and imported into Basecamp - copied to Etrex.
When trying to follow the route the map is not visiible, only a white screen shows.

To resolve I had to:
a. delete ALL nearby routes
b. Delete All nearby Waypoints.

Only after this did the map show.

So, I have no chance to see a route over laying the map.

Maps are paid for high detail ones. (UK local sections).

Question; Is there something else to do to have off road routes visible together with a map?
Its not much use without the map.

There is a difference between a Route and a Track (See this Link), was the 'trek' sent to the Etrex Touch 35 from Basecamp as a Route or a Track ?, if you sent a Route then the maps used in Basecamp and the t35 must be the same
