How to switch on the ups, the sreen show nothing

Turn it back on in a different location and give unit time to hook up to overhead satellite. If nothing then best you call Garmin for guidance.

Sound like the videocard is bad or possibly a bad ram stick.Check it with an external monitor.If it shows video on it ,the card is ok.If not the videocard is bad.If it shows video, the ram may be bad or the connection to the motherboard is incomplete or the plug is bad.Also unplug the HDD then try to start it up.If the bios is readable the HDD is causing a conflict.

This is an indication that your map unlock code has either been corrupted or is missing. Please see this link for more information on this problem.
