Sorry but I posted this in the wrong forum so here it is again with an image..
I have recently bought a Garmin 600 and on my pc I have Basecamp and have downloaded a Birdeye map of my area.
When my Garmin is connected I can see I have a choice of Gobal map and TOPO UK map. I have TOPO UK selected because it gives more detail. However when I disconnect the Garmin the TOPO UK map is not available rather disapointingly. How do I make it available when the Garmin device is not connected?
