Zumo 660 gps MISSING SYSTEM SOFTWARE message issue (Solution)

[Falken561]

I want to share my experience after tried to update latest available maps from Garmin (thru Garmin express). Everything was ok until the update was completed then I restart the gps and a message pops up right after I turned it on: "Missing sytem software", then it get frozen. Only chance was turn it off or on but always showing the same message. I found a old forum that helped me out so quick, I just followed the instructions and it came back from the death. Here is the forum and post: http://forum.gps-expert.nl/viewtopic.php?t=598
I tried to check the forums here but I coulnd't find the same problem (maybe I was blind ....). I hope it can help (eventually) if someone else get the same issue.

Glad you got it fixed. I had some issues before & while on phone with Garmin tech learned how to do a HARD reboot. Problem there is express failed to back up my unit properly & lost ALL my save data. Month or so later a message appears import new data? & thankfully it was the missing info. No clue how or why just glad it did immeditely found a SD card & transferred the info. Now before new updates I double check & save any favorites to the card & eject it ;then preform update, all goes well put card back in & on about my way. With all the updates there still seems to be a fat finger typo around E Texas.
You input the address where your standing as a destination & it will try route you bout 6miles in any direction not just Garmin mind you but Google & TomTom too. Funky. Glad the zumo also has dealers phone # most are aware & can guide you from wherever it mislead you to. (what dealers that are left that is)
