I bought one of these from a pawn shop for about $30 because they thought it
didn't work. In fact they just were not patient enough to let it do a cold
start.
The connector plug you need is a 5 pin female Lemo connector. I'm sure you
can buy these from electronics parts suppliers but they are pretty
expensive. Probably cost as much as my Magellan. I have been looking for
them on eBay but not seen any female connectors yet.
According to the manual the unit will run on 10 to 15 volts DC from an
adaptor.
The wiring for the plug is as follows:
If you look at the female plug you will see a small rectangular indentation
which matches a projection inside the Magellan socket. If you position the
connector with the indentation at the bottom (6 o'clock) the pins are number
1 to 5 in a counterclockwise direction.
pin 1 chassis ground (- DC) (5 o'clock)
pin 2 transmit data (2 o'clock)
pin 3 receive data (12 o'clock)
pin 4 + DC ( 9 o'clock)
pin 5 signal ground (7 o'clock)

Hope that helps.

I am a newbie to the group, so ask your indulgence if I offend any
protocols
here.
I have a Magellan 5000 GPS unit given to me. I think it is about ten years
old but it works very well. It requires either 6 dry alkaline AA batteries
or 9v dc through a dc/dc converter from 12v which was once available from
Magellan
dealers. I have tried the internet through many sources to find one of
these
converters as the machine goes through alkaline cells at a great rate, but
with no success. My query to the group is- the handbook shows a small 5
pin
plug into which you plug the converter. Is this a standard plug that I
could buy somewhere and if so which of the pins carries the 9v dc?
Finally, will the machine blow up if I feed it 12v dc?
