For me there has not been any issue with software or maps for Peaklife.
I am currently running Igo Primo 2 with the current 2012 maps from Whereis. Been using this GPS on some very long journeys and it does all I need it to. My current screen on the GPS shows the normal stuff but also allows for two lots of statistics as I ride... the the total distance, estimated time etc., of the total ride plan and the same information for my next waypoint all on the one screen, very beneficial for my rides.
Igo Primo runs on Win Ce (which is what Peaklife has) there are versions of the software for Iphone, Ipad, and Android so should run on Galaxy phones and tablets as well.
maps are obtainable for purchase from naviextras.com
Now where was I
