Wiring diagram for Gramin GPS to VHF interface

I have purchased a Garmin GPS Map 551 and Garmin VHF 200i and I am planning to wire them in, have looked at both manuals and somewhat confused as the wires shown are not coded the same - so can I get a better version anywhere else?
Also can I also add a can I add a Garmin 300c Fish finder too so they can all talk to each other?
Hope someone can help?
Lemoney ;O)

I've had a quick look at the online manuals and you would be better off utilising the NMEA 2000 network rather than the NMEA 0183, it's just plug and play with no need for wiring. If you ask whoever you bought the GPS and VHF they should be able to provide the correct cable.

What Cookee said, but not sure if the fishfinder is is NMEA 2K?

I just pulled the manuls for all three of them, may be in luck - they all seem to run NMEA2000 if you believe the sales leaflet, but read on....

It looks like Garmin have taken the opposite view to Lowrance and you don't get the NMEA 2K cables included so you may need to go shopping, andyou can then literlaly "plug'n'play as per

http://www8.garmin.com/manuals/3307_...ctions_EN_.pdf

Page 8 of the PDF. The "other devices" are your VHF & your Fishfinder.



Now, assuming you donl' want to go out & buy a load of NMEA cables & Ts, based on

http://www8.garmin.com/manuals/3307_...ctions_EN_.pdf page 7
and
http://static.garmincdn.com/pumac/30...structions.pdf page5


Plotter to VHF

Plotter Black to VHF Black (also doubles as VHF power -ve by the looks of things)
Plotter Blue to VHF Purple
Plotter Brown to VHF Blue

Fishfinder to Plotter

I am now confused. Pulled the manual for the fishfinder,
http://www8.garmin.com/manuals/Fishf...structions.pdf
only to find no mention of NMEA2k, even having seen it talked about in the sales bumff!

If I am reading this right, you might be better building an NMEA2K network between plotter & VHF, then connect the fishfinder to the plotter using the 0183 wires thus:

Plotter Black to Fishfinder Black
Plotter Brown to Fishfinder Blue


2k is certainly the easier way to go, however check your plotter manual for a 2K port - I may have dug up an older version of your fishfinder.

Might have been better to buy the 551s (sounder version) plotter. With an add on transducer which plugs straight in you'd get both from the same unit and use the N2k for the radio..

That's what I suggested upon purchase, I think you wanted to use an existing fish finder though didn't you Sophie/Steve ? the sales patter suggests it's simple to link the gps to VHF with fittings in the box, I think linking the 3rd standalone unit is where it becomes a little more complex. As I said at point of sale it's not something we specialise it...yet

There's not much difference in cost between the 551 & 551s models, well at the trade price you got it for anyway

We're neighbours! I know where you are - near Plymouth Sailing School - I'll drop in next time I'm in Plymouth.

Thing is both plotter & VHF run 2K, so it's a simple case of a "mini network" between those two and then use the 0183 to feed the sounder data to the plotter

If in the fullness of time the fishfinder dies, anything new wil lhave 2K by that point & it becomes "plug'n'play".....
