How to know the Garmin Nuvi 255w battery charging has completed

If you are charging the battery of Garmin Nuvi 255w using a USB cable connected to your computer, there is a way to know the charging has completed, although not so straightforward.

You need to firstly unmount the USB storage(s) in your Garmin Nuvi 255w detected by your computer.

If you are using Windows, right click on the Safely Remove USB Device icon in the taskbar and select "Safely Remove Hardware". Then click the Stop button follow by OK button. Your Garmin GPS will reboot by itself and go into normal operating mode which you can use it and navigate as usual.

Now, slide the Power key on top of the GPS to the left to switch it off. If the battery is still charging, it will show the message "Charging Battery. Slide the Power key to turn on." before the screen turn off. If the battery is fully charged, it will show "Charging Battery completely. Slide the Power key to turn on." instead.

In fact, the GPS is not off when it is still connected to the USB, only the screen is turned off. You can always slide the Power key again to turn on the screen, and slide again to check for the charging status.

From the message, you'll be able to know if the battery charging has completed or not.

Mine reconnects to the computer when it reboots. I had to instead:
1. Plug in to computer (it connects)
2. Unplug (it goes to normal mode after a few seconds)
3. Plug in again as soon as Loading Maps appears
4. It then stays disconnected and starts up
5. Turn off and you get the charging screen.
