Well done gnuite, the installer file is the biz."
http://www.gnuite.com/nokia770/maemo-mapper.install" and after the successful install, I fooled the GPS screen into thinking the iMac was a bluetooth GPS to allow the program proceed to the mapping screen. Now I will purchase on eBay a suitable GPS to pair with it. anybody got a clear favourite unit?
This application is mind bogglling in its possibilities as I sail boats offshore as well as drive a car and getting lost is not an option in one of these activities. thanks muchly paulclan
