Navman iCN520 Autolock file

[nalagnik]

Although the file Autolock.rgn is on the supplied Navman SD card with the UK maps pre-installed ( can see it using a card reader attached to the PC). When I use SmartST 2005 to download maps from my pan-europe cd onto a blank SD card this is done OK and the new SD card works with the new country map loaded. I note however that there is no sign of the Autolock.rgn file that I expected to see and presumed it was written to the SD card by the SmartSt 2005 program. What does it do and is it important and if so how can I create it? Curious 8O
