Cobra MR-F55

[joblogz]

Anyone got an idea on how to get the gps lat / longs from my Raymarine C70 to my Cobra MR-F55.
Radio's display stuck on the startup load of 999999999999s
It's wired to the NMEA out wires from the C70 but nothing happening.
Grateful of any help with this.

NMEA connections on the cobra are made via a 3.5mm plug- and there are 2 similar sockets on the back, a stereo one carrying the NMEA and a mono one for the cockpit speaker. on at least some versions of the manual, users were directed to plug the NMEA plug into the speaker socket so maybe start by checking that connection.
