I got my 188c wired to my ICOM 601 done by a chap at Cobbs Quay, just sent him the wiring and relevant plugs and it was done and back in 3 days and cost £15, if that is of use to you, squire

thanks for the message, i am wiring the garmin to the VHF DSC connections but also have NMEA connections as well which i am looking to connect to the smartcraft to see what i will get. After i informed Garmin that their diagram may be incorrect for wiring assignments they are sending a revised copy.

Not sure if Turbo diesel or other marine elecrician will know if smartcraft are compatible with garmin?

When I connected my Lowrance Plotter NMEA to smartcraft I used the information below - Cannot remember where it came from .

In summary:

Smartcraft White = Garmin Brown (NMEA out)
Smartcraft Blue = Garmin Ground

Some of the other info regarding NMEA versions may be usefull if it doesn't fire up at once.

Cheers

"I am using a GARMIN 12XL. It is connected to the Smartcraft
gauges via the blue and white wire pair. The white wire is
connected to the brown wire (NMEA out) coming from the GPS set
and the blue wire is connected to ground (0 V). In the setup
meny of the GPS it is possible to select between NMEA 0183
version 1.5 and version 2.0. Version 1.5 works OK, although
the track reading of the GPS differs exactly 2 degrees compared
to the speedometer display. At power up of the Smartcraft
instruments, it seems that version 2.0 initilaizes time, but
after about 30 s the text 'NO GPS DATA' appears on the data
display of the speedometer. 4800 baud rate is used.
Is that an answer to the questions?"

Phil, thanks for posting this

i will be interested to see what Garmin send me as he agreed the pdf file on the Garmin site is incorrect and he had a hard copy of the correct wiring setup.

i agree that the smart craft have a blue and white cable for Nmea connection, but what is not clear from the garmin documentation is which cables to connect from Garmin, they have a blue port 1 data out cable, a brown port 2 data in cable and a ground as well.

ok, today i received a revised wiring diagram from Garmin.

they are attached below for fixed gps, hand held gps and a fish finder gps

the fishfinder gps is different to the pdf files on the garmin site and different to the layout in the manual. I can not comment on the fixed gps or handheld gps diagrams

i had originally called Garmin as i believed their documentation to be wrong, and this is what i got back

are there any experts out there that can confirm they have wired a garmin fishfinder gps to this latest diagram and it worked and can i ask what info they got.

Garmin NMEA out goes to the Smartcraft NMEA in or GPS wire as per the Smartcraft wiring diagram - the earth is just a common one ........ worked first time for me!

You end up with GPS speed reading, fuel to next waypoint etc, and if you have the 5000 series instrument it even repeats the heading information to the next waypoint!
