Multiple GPS Speedos?
Can more than one GPS speedo be wired in a series (or parallel) with the same antenna source? I'm thinking about an extra speedo for the passenger side, but don't want to pay for a second antenna. Thanks.

Yes,
I am running both a 3-3/8" Gaffrig and a 5" Autometer directly from my Garmin.
Only one of them will accept the NMEA high-speed protocol, but both will accept the standard NM|EA0183 output.
You don't need a separate antenna at all if you have a GPS with NMEA output. You could wire up 5 or however many speedos you wanted, and they just suck the speed data off the CAN bus.
