just bought a home Adaptor Charger for my Nuvi 200w.
I have 2 unit of Nuvi 200w, one is Taiwan version and other one is USA version.
Taiwan version is no problem for Charging but
USA version seem unable to charge because when I plug in the charger,
the screen will show as Data Mode. Try slide the power key to turn off it,
But failed to turn off, must unplug the charger.
After Thinking a while, I think may be It has some method to charge the USA version 200w.
Yes, I get the method to charge my USA version 200w.
Before plug in the Charger, turn on the 200w.
On the Right Top has one Battery Icon, Press and hold "battery Icon" for 8 seconds and go into Service Menu.
And now I can plug in my home adapter charger, once plug in can hear "dui" sound and at the Service menu screen,
can see the Battery on "Charging". Press Exit button to out service menu.
On the main screen, the Battery lcon will be hidden when the battery is charging.
While it is charging, I still can use it.
