Has anyone ever done it?
I understand that power requirement for the GPS is higher than older HB units can support, but can we connect the GPS directly to battery with in-line fuse? I read through the NMEA diy cable article and saw the red (power?) cable in the GPS pig tail, which makes me wonder if this is the power supply to the unit.
On another note. Does the GPS puck supply NMEA data to the head unit? I thought the signal would be in some raw format (rockwell whatever.. I think) direct to the head unit rather than NMEA.
Looking forward to your informed input.
