edge 705 - problem with cycle routes and contours

I have downloaded a premade cycle route map and a contour map from 100820-GB+Contours-Routable-GMAPSUPP.IMG for the UK.

With the cycle map I can’t see any cycle routes labelled.

With the contour map I have downloaded it to my SD card and can’t select it.

Has anyone managed to download either of these maps to an Edge 705 and got them to work ?
