Put in your new QuickCure RGN file characters and bingo. Loaded up successfully and my Zumo 550 now shows up on my Windows 7 pc screen.
Have now found on the internet and loaded RMPrepUSB v.2.1.734 and opened up the window.
Now comes the fun Butters. When I can get my head around this format tool why does it not clear out the file I have just downloaded into my 550 and have to start all over again?
Sorry playing around with pc's is not my strong subject.
