Alright Brainiacs... Little help.....

[STEELA]

Finally got accessory cable from Uniden to connect GPS to VHF.

3 wires.
GPS NMEA Out to VHF
Ground
Power

I connected all three, turned on NMEA Output in GPS.

VHF reads "waiting for GPS signal"

I have Lat/Lon readings on the GPS.

3 stinkin wires. NMEA "ON" indicates Baud rate
at 4800.
Humminbird told me I don't even need the power wire connected.

Frequently you have to tell both units to either send or receive. I don't have the manual in front of me but it should be in set up. And the baud rates need to match.
