Help setting up Lowrance network

[Camhawk88]

Well I managed to pick up a pretty good buy for my electronics- 4 year old pristine condition Lowrance gear.
I have-
1x LXC27 sounder 7" screen
1x Global map 7200 7" screen
1x 2kw Radar
1x 2kw radar processor
1x broadband module
1x transducer
1x extrenal GPS arial(not pictured).

Now I need to find out how the hell to put it all together.

The leads I have are a broadband lead, transducer, radar lead, power lead for the broadband module. I have 2 power leads on order which incorporate NMEA.


Also the GPS antenna (not pictured) has a 5pin plug- 1 pin each 'corner' and 1 pin in the middle. I dont have any input jacks on any of the gear that fits up to it. How is this meant to attach?

See below photos. If anyone can help with a schematic of how these should all fit together and if there are any other leads I need please let me know.

The gear
97217

Broadband module
97218

Radar processor
97219
Sounder
97220
GPS
97221

Thanks in advance.
