iMac running OS X Yosemite 10.10.1
Basecamp (check for updates) says 4.2.4 is the latest version but I read here 4.4.6 is the latest. Can I just download 4.4.6 and not loose anything.
Background - I've a Zumo 500 since 2008 that is now dead. Rather than repair I'm contemplating either a Zumo390 or Montana600 for Motorcycle use - 70% on road pavement 30% gravel off road dual sport.
Is it because I have only the Zumo550 linked to Basecamp I'm stopped at 4.2.4 version?
