Okay, I bought a secondhand Zumo 660 last year from a fellow Tosser. Tonight I decided to finally connect it to my computer (Mac), register it in my name, check for map updates etc (it's loaded with City Navigator Europe 2010). All was going swimmingly, I downloaded the latest Garmin Communicatorplugin for Mac, created an account with Garmin, the Zumo was detected, then I clicked to upgrade the system software and followed the on-screen instructions - disconnect the device from the computer, manually turn it off then back on again etc. Trouble is, when I went to re-connect to the Mac there's a message on the Zumo screen saying System Software missing and now it won't do jack shit - Mac won't detect it, Garmin software won't detect it...
Anyone else had this prob and know of a solution.
Time for me to Google...
