On the Navigator Garmin Dakota 20 crashed touch screen (in Dakota 10 uses the same touch-screen).
New available on various Chinese websites, and then replaced.
Consider the sequence of actions necessary to replace the touch screen.
Remove the back cover under it 6 small screws that hold the case.
Unscrew them and the navigator, you can disconnect into two parts.
Now two of the only trail connects the screen. Disconnect it and divide the parts.
We are interested in a part of the screen.
The screen is too screwed. Unscrew 4 screws and take out the screen from the body (it rests on two latches at the midpoints of the side parts).
