System software missing Oregon 550T USB inaccessible.
I can't manage it, I've been busy for hours and days with all the tips, but I can use the mentioned program Updater.exe and I have also seen other program names that you have to put on your SD card of max 32 MB in the folder with Name GARMIN, after which the system software should start again from the SD card, for this you still have to turn it off - remove the batteries, insert them, connect the USB, put your nail in the top right corner, but without a program I can't get anywhere. Because it does not recognize the USB, I cannot use the web updater, which also means that Garmin Express is out of the game. Who oh who can help me further?
===============================================
Download and use Garmin Express as a clean install. Use the Web Updater. Make sure the Device is registered on the Garmin website. I am on my third Garmin Auto GPS and never had a unit that couldn't be reset or updated.
