bloody electronics

No such thing.

Connect the red and black to power, connect the Cobra NMEA OUT to the Raymarine NMEA IN (+ to + and - to -), set the baud rate on the plotter to 4800.

Might help to post links to the Cobra and Raymarine manuals so people can verify your quoted colours are correct.

Edit, Just checked in my Raymarine installation manual and you are using the wrong wires, you are using the NMEA OUT wires. You should be using:

Orange/White +
Orange/Green -

You still need to check the baud rate.

You could also change the thread title to "Bloody amatuers" :)
Orange / white to what ,,,, Orange / green to what
 
seems that your mfd has 3 nmea0183 ports.
port 3 is IN only and 4800baud, wouldn't it be easier to use just that, no need to mess with configuring menus on the mfd!
that's listed here on p34:

blue/white + blue/green -


doh, sorry repeated what Baggywrinkle and possibly others typed 10mins ago... didn't refresh before typing...

Nmea port setting ports 1. 2 and 3 are now showing 4800
assuming you get the gps antenna working, remember that if you decide to fit an AIS receiver, the port you're going to use must set to 38400 so gonna be port 2. So you may have to move mushroom to another port for that.
If you're going to get a VHF as well in the mix that's probably going to be in port1, hence the suggestion to get the mushroom on port 3 to start with and not having to move things about at a later date

Thank you , that is nxt job
 
Wires done as suggested , just giving it abfew minutes as suggested ?

Fingers crossed ..... if it doesn't work, try Port 3, the Blue/White, Blue/Green .... just noticed you want to add AIS ... that will need to go on Port 2 as vas mentioned as it is the only port which will do the 38400 for AIS.

... so I'd move it to Port 3 anyway, or you can't connect your AIS later.
