The third (white) wire is a so-called "sense" wire. The sense wire "tells" the cigarette lighter adapter that the voltage on the DC input
to the GPS is different from the nominal 5V.
The GPS has a internal Lithium Polymer battery, with a life of 3 hours. Maybe I'll forgo all the hassle and just use it cordlessly
and charge it at home as needed, or in the car when not in use.

The above post came up prior to my previous reply, which is now redundant.
The plug in effect comprises a rather sophisticated switched-mode type, regulated power supply, required in order to provide a reliable five volts.
It would be stupid to mess with it in any way and it will be best to connect it via an appropriate socket. Excellent protection facilities will be incorporated and an individual fuse is not required.
Yes, forgo any hassle on several counts. It will also be an advantage to “exercise” the internal battery.
