276c Map Versions

[dicktheleg]

Hi - I need to talk someone who is selling a 276c through what to do to find out what mapping is installed - can anyone tell me what buttons / menus they need to press to access the installed mapping?
Thanks
Rich

From the map page ie. map on screen
Press MENU once
Scroll down to MAP INFORMATION >>> press
