I was wondering if it difficult to get an original garmin map file from an original garmin purchased data card. I ask as I am thinking of buying the (garmin) deleted missing title 'rannoch moor and loch tay' and uploading it here (or getting someone else to do it!). Do you have to hack into it using a linux machine or something more complex or is it just a case of copying the image file and uploading it? Thanks.
