Treated myself to one of these recently with 1:25 mapping for all of UK.
Worked fine in lakes but when I went to check a route i'd plotted for Snowdonia I can't view mapping in 1:25 format. When you zoom in after 5km it switches to OS mapping but not for Wales or one part of Scotland (think its south). The mapping is made up of 5 tiles - North Scotland/East England/North England & IOM/South Scotland/West England & Wales.
Everything is enabled as it should be and as per Garmins instructions and it was delivered setup.
Have switched the card to another unit I have, extrex20x, and it all displays correctly.
Just doesnt work as it should in teh GPSMAP 65s.
Anybody offer any advice or had the same issue.
Thanks
