Somebody said that they had used the cigarette lighter for power. Just remember
that the little bugger needs SIX volts and that the regulator is in the ciggie
lighter plug. Connect the Roadie directly to 12 volts and you have an expensive
lump of silicon in your hand.

Whoa. Thank you, Jim, for the warning.

I powered it from a version of the GPS adapter panel, put a 6 volt regulator on
the backside of the panel, the GPS antenna connector on the same panel, and it
looks like a factory install.

As someone who only has the basics of electronic knowledge, I am
confused. The cigarette lighter plug shipped with the Roadie is not
designed to reduce the voltage to the correct six volts?

If not, what parts would I need (the GPS is an IFR-certified panel
mounted model) to power the Roadie in the aircraft? Is there an off-
the-shelf solution?
