Base from the description of your problem is seems the issue here is the software of your unit got corrupted and what we can do here is to try resetting your unit.

So follow these steps press the lower right hand part of the touch screen and while pressed turn the unit off/on. The system boots up and asks if you want to reset all the user data. answer yes or a master reset.

After doing the reset and still same problem the unit needs repair already and better send it to Garmin for repair.

Gpsmap 5012 system missing

There is no reboot or recovery software for this problem. You are going to have to send the 5012 to Garmin for the factory reflash of the EEPROM.

Have cleaned the brew unit and the machine still does not work

If you are holding the brew unit in you hand look at the top you will notice a small knob with grooves, if you look to the bottom of that knob about 3-4 inches inside the unit you will see the screen. If it is no noticeable run water from the faucet over the brew unit.

System software missing garmin 250w

If the unit indicates "software/firmware missing", then you can only try to re-install firmware by running WebUpdater again. If it doesn't work, then the unit has to be sent to service to have it re-flashed.

Reseat imaging unit notice won't go away

The Phaser 6250 has a known flaw in the design of the gear slide assembly associated with the door over the imaging unit. One of the teeth has skipped and will require a service tech to "realign Rack-V". It's an easy fix if pictures/diagrams could be posted, but I'm not recommending a novice to attempt this fix without them. "Reseat Imaging Unit" error is a common fix for Xerox printer techs familiar with the 6250.

System software missing

Just had this problem over the weekend. I emailed Garmin and received a zipped file to reinstall original software with step by step instructions. It took about 6 minutes to do and works perfect again. Go to the Garmin website and email "software system missing" issue to support email address. Have your serial # handy. I received a reply in 1 business day. Hope this helps!
