Richard Ray, GPSNavX, MacENC and iNavX, has formally confirmed to the forummacsailing.net forum he had long been practiced :
« When MacENC or GPSNavX is purchased, it can be installed on any Mac owned by the buyer that it wishes. An activation code is required for each computer, just send a request by mail to support gpsnavx@mac.com to get one. We do not believe it is fair to charge for multiple installations or upgrades of software. »
This deserves to be commended !
