I saw an item on the Pfrank site about making a clone cable for Garmin’s.
You cross over the data in and data out wires and can clone one GPS to
another. I’ve been thinking about upgrading my GPSmap 76 to a color
model and this would save a lot of set up.

Does anyone have any tip or experience with this? Can you transfer the
Blue Maps or is it just waypoints and setup info?

I’m running a power and NEMA cable to my steering station. Does the RF
suppression bead have to be on the end near the plug as it is on most
prefab cables? I’d like not to have it clunking around on the cable
unless I really need to. Can it be inside at the other end? Does the
choke just slip over the cable or does it need a connection to the
shield or conductor wires?

BTW USB cable works just right for the Pfrank plug. It has large red
and black conductors for power and a smaller white and green for data.
