I am a newbie owning a Garmin Oregon 550. I have been trying to access maps for Great Britain Discoverer National Parks 1:25k - particularly Brecon Beacons, Pembrokeshire Coast Path & Peak District - but any of the others (Lake District & Dartmoor) would be good.

As I am unable to access Megaupload (a BT Internet issue I think), are there any Mirrors.

Many thanks
