Be VERY AWARE.. i downloaded a Beta previously only to find that it's "licence" ran out
(no mention it was a limited version when downloaded) and left me unable to use the program or roll back to the previously installed version.
Fortunately a non-Beta was released just after my problem which i could subsequently download and have had no problems since...
Personally i'll never download a Beta from Garmin again, had i been travelling i would have been caught short with no mapsource to plan my trip on!!!!
Just thought i should mention my experience as i'm sure others won't realise this potential issue, i certainly didn't until i was caught out by it.
HTH - Stu.
