Hi Catymag,
I have some troubles with sending the CNEUNT2010.1 - UK maps to the GPS - Ireland works well but not the UK. It always stops after 100% Building index completed ...! I tried it with 3 different GPS (StreetPilot 2720, Nuvi 205, Oregon 300 and last but not least with a empty SD Card.

Any idea what could be wrong? I deinstalled/installed mapsource twice (6.13.7 and 6.15.6) with always the same result.
Regards
Erwin
