GEONAV 11C: sourcing 7pin male plug for GPS antenna?

[vas]

good afternoon,

a friend had some issues with his GEONAV 11C (that at the end turned out to be vertigris on the power cable with screen flashing in and out) Today I swapped cables with a spare he had, plotter is fine working on my bench power for 5h, so call that fixed.

Problem is that he thought his problems had to do with the GPS mushroom (don't ask why, dunno!) so went up the arch of his 80s P45 and tried to remove it. In doing so, thought the plug was a screwed on to the other side (which is push and twist...) so he royally fcked up the 7pin plug/socket combo.
Now, checking on the online manual, I see that the gps mushroom is a NMEA0183 one, so needs V+ GND and the NMEA+ and - out. Easy solution is to cut both sides, identify the cables and fit a 4 pin waterproof combo up there.
Haven't seen the full mess, mate says the arch side connector is fine, the one I've got here has half the pins broken off (and pretty sure nicely stuck on the other side...), so my Q is:
can anyone point at where I can source a male 7pin plug I could solder onto the short cable coming out of the gps mushroom?
The quote for a new gps antenna here in Greece was 230euro or something like that.

Unless I get a cheap plug, I plan to simply cut the plug, identify the 4 cables and fit the mushroom under the f/b dash next to the plotter hooking it up to the main power/nmea cable of the plotter ignoring the extension to the f/b arch.

cheers

no replies, so a different question now

said plotter was on the f/b and mate has been putting it on and off each time he was using the boat. After spending umpteen hours trying to find what's wrong with it, and even using another raymarine gps 120 (or 125) nmea0183 antenna that worked fine (after replacing the CR2032 battery of course...), turns out the bloody NMEA0183 IN+ pin on the multiplug thing on the plotter is missing - broken and gone :-(

I'm going (as a temp measure) open up the thing, and resolder NMEA0183+ in to another pin (hasn't got anything else hooked up to the plotter afaik)
Any chance of finding another such 9pin plug or socket however you call these want the one that mounts on the plotter with the pins striking out (male!)
p11 of the manual here: http://geonav.kgk.ee/others/geonav10c/G10C11C Platinum - EN.pdf

any suggestions?

fwiw, have the aux 7pin plug, tried to wire the gps n0183 antenna there, nada! probably different baud rate.
Mind, anyone knows how I can get to config menu in this thing? hoping I could change baud rates and get it working without having to open up the plotter and start soldering about...

cheers

PS. things like that make me really LOVE N2K!

I wanted to fit an old garmin chart plotter with built in gps by my chart table but it would be surrounded by steel so would need an external active gps aerial.
I used a puck type one for cars. Very cheap and aquired signal far faster than the built in one ever did.

true, my problem now is that I have two gps mushrooms NMEA0183, but no way to wire them to the plotter due to a bleeding broken pin n the plotter :-(
btw, are these also nmea0183? thought that most of them are simply usb

I opened up the garmin and saw two wires connected to its antenna.
I fitted a socket in the garmin case that matched the plug that came on the puck antenna.
Nmea didn't come into it.
Yours sound overly complex compared to what I did.
