ive looked at the map chart update for best european maps, the 1 i think is the most update and best to install is western europe 910-4892, however the tech guys on here sometimes disagree and actually say go back to 905 set, especially when iwas install the french map.
at present i have
france 905-4754
uk roi 910- 4892
my config
Microsoft Windows XP [Version 5.1.2
GetMy-CFG v2.53
