Hello and sorry you're having problems. Can you please get me the Brand and Model of the GPS so I can look into this?
Thanks for the reply. This message indicates there's no DC coming into the GPS from the micro USB port on the unit, and the first thing you would need to do is plug into another port in the vehicle (your 12 volt plug may have blown a fuse?). If you can confirm the car's jack is working properly then the next step is to purchase a new cable as these cables are prone to wearing out at the ends where they connect. You can purchase a new charge cord at the link below for your Garmin:
This is the MOST likely cause of this problem, but without testing out a new cable first- there is no way anybody could be certain. The next possible cause is a faulty charge port or even a faulty battery in the Garmin- but this is much more rare and it's more likely that you simply have a bad 12 volt plug i the vehicle or a bad cable.

You can also try using the current charge cable you have (if it has a detatchable USB plug at the 12 volt socket) and plugging it into your PC to see if the GPS will power up or if it still gives that same message. Troubelshooting it running through removing of variables to see what the root cause of the problem is.
