Link the input wire from the Furuno to your PC also to the Uniden,
since it is obviously working and transmitting NMEA sentences.

In the interest of brevity, I didn't mention that the two outputs
(data 1 and data 2) are also labelled "Current Loop" and "RS-232C" so
they must have different electrical characteristics. They share a
common return terminal on the GPS.

I've sent the question to Uniden also.

RS232 refers to a data-carrier, the term Current Loop could well refer to a
power loop, i.e. 12-volt positive. If you were to continue the data wire and
extend it from the input at the PC end, your VHF would receive the signals
without interuption from your PC.

Remove "nospam" from return address.
