Re: Navigator I Won't Power Up
To remove the Navigator I:
There are three connectors: the knurled antenna connector, the four pin power connector, and a earphone-type plug. Disconnect these three.
Then there is a knurled knob on a screw holding the Navigator to the frame. Loosen that screw. Press down slightly on the GPS and it should pop out.
When it's out, put in a new set of batteries, being careful to observe the polarities.
At that point, it should power up (though it won't give you any GPS data because it's not connected to the antenna).
