Re Magellan GPS 310
There is/used to be an external power supply/data cable available from Magellan @ ~ AUD$60. The manual says the external supply is 3.3v @110mA. I tried this voltage from an external power supply, but it was not sufficient to reliably turn on the internal electronic change-over switch.
So I have made up my own mobile supply using a cigarette lighter type mobile phone car charger (nominally 5v, but you may wish to lower the output voltage by adjusting one of the output control resistors attached to pin 5 of the (probably) MC34063 DC-DC Converter IC in the power supply). A connector plate using a piece of plastic with small machine screws or rivets to line up with the terminals is attached to the GPS using anither machine screw into the brass nut moulded into the rear of the case. You could use a similar system to use a USB connector to attach the GPS to your laptop for mobile mapping, also.
The external supply/data connections are on the rear of the GPS310, above the battery cover. Looking at the rear of the GPS 210, the top left terminal is V+ and top right terminal is V- whilst the lower left terminal is Data In and the lower right terminal is Data Out. Hope this helps.

I'm not sure that there is a car charger available for the GPS 310. There is no external port where you could plug it in, the only thing you can do for power is take extra AA batteries with you.
