I hooked up the NEMA output from my Garmin GPSmap 76x to my Quest radio this
morning.

The radio has a NEMA in and NEMA out line and shows them connected to wires
of the same color for a GPS by the same company. A few pages later there is
a table for NEMA connetions to various brands of GPS.

Both fixed mount and portable Garmin's show the NEMA out line from the GPS
to be connected to the ata In" in line on the radio. The radio "Data Out"
line is indicated as connecting to "Black - Neg Ground". I therefore put a
wire from the ground block where the black negative lead from the GPS power
cord attaches and ran it to the Quest radio "Data Out" lead. I'm sure this
is what it said to do but it seems odd.

I haven't turned anything on yet so, if anyone can confirm that I did it
right or head off melting something, I would appreciate it.

Please: only if you know. I hate those post responses that start out, "I
haven't got a clue but here is what I guess."
