I am also going to the UK (Ireland) soon. I see you have the 60CX GPSr which is basicly the same as my unit a 60CSX. I bought the MicroSD card for my unit that has just the maps for the UK, England, Scotland & Ireland. The maps look as good as the maps I have for City Navigator US. I think I paid $110 which included shipping. I'd have to check when I get home where I got the maps. Checked where I got my maps, (MobilePlanet) Item #136295 Garmin City Navigator NT microSD Card (UK, Ireland)
