I have a Start 25 which I have been using for several years with few problems. It is normally updated weekly.
The latest update involved downloading a new Europe map, so it was a big one. It was interrupted, and the Start25 would not then restart properly.
After various disconnections, computer shutdowns etc., it eventually started to show "No Maps Found" - and the memory card which had contained the map is indeed empty.
I should be able to use MyDrive Connect to download the map again, and sort the problem that way - but although the map is shown as available in MyDrive Connect I can't download it because the Start 25 doesn't connect to the PC. It starts the connection process, and shows as connecting, and then shows as Not Connected.
I've tried it on another Windows 10 computer with the same result.
I've gone through all the procedures outlined in FAQ, including uninstalling/reinstalling MyDrive Connect, and trying to update the driver. But I cannot see a driver in Device Manager.
My computer runs Win 10 Home 64-bit, fully updated.
Nothing significant on the computer has changed since the device was working and updating normally.
