[Mgs] GPS/Nav in a MG - blind and deaf

[Charles Hill]

John,
I'm not going to get in the discussion about the pros and cons of using 
a GPS.

As for connecting a GPS to a positive ground car, don't use the in-dash 
lighter socket.  I have an add-on socket from the local auto parts store 
on my positive ground Morgan.  It is fully encased in plastic so no 
chance of a short circuit.  I simply wired it backwards.  The negative 
(black) wire is connected to an unused accessory terminal on the 
ignition switch and the positive (red) wire is connected to a convenient 
ground.  I zip-tied it to a support bracket under the dash.  It is easy 
to get to and out of sight when not in use.
