Do you know if the Garmin zumo 660 power mount can interchange with the
Garmin nüvi 670?

I was discussing GPS with a friend of mine a few thousand miles away who
has a broken Garmin zumo 660 but a good power mount. My working Garmin nüvi
670 has always had the colored wires sticking out of the power mount
fingernail-sized flat clip.

My friend offered to ship me his Garmin zumo 660 power adapter if it will
fit the Garmin nüvi 670.

Pictures on the net and a visit to the store seem to indicate they look
mighty similar - but who knows if the electronics are the same or not (I
don't use the FM traffic feature).

Does anyone know if the Garmin zumo 660 & Garmin nüvi 670 use the same
power adapter? How can I tell w/o destroying the equipment?
