Garmin 720s - Livorsi Speedometer
Hello! I know there is lot of threads about this and I think I have read all of them but I cant find any good answers. I know that its possible to connect the Garmin GPS antenna to the Livorsi Speedometer but it doesnt work when I connect the cables. There is one yellow cable ”NMEA 0183” from the tac gauge. This is the cable you connect to the Livorsi gps antenna and also the cable you want to connect to the blue cable from the Garmin GPS, right? I have connect the blue and the yellow cable, but it doesnt seem to work. Thanks! /Johan |
What year is the boat and how old is the LIvorsi. Do you have any pictures of the wiring and the back of the units?

Need to figure out if it is Really NMEA 0183 or 2000. If 0183 you have to configure that in the setup as stock setup is defaulted to NMEA 2000

Chris The Livorsi gauges is not that old I think. Everything runs with the SmartCraft. I have a picture of the backside of the Livorsi Speedo. I can take more pictures of the wiring and the other gauges tomorrow. https://cimg7.ibsrv.net/gimg/www.off...6fe4df79b.jpeg |

Chris Also some pictures in the Garmin GPS configureations. I did a factory reset. https://cimg1.ibsrv.net/gimg/www.off...addeab304.jpeg https://cimg0.ibsrv.net/gimg/www.off...6edf8320b.jpeg https://cimg9.ibsrv.net/gimg/www.off...f77b9be30.jpeg https://cimg8.ibsrv.net/gimg/www.off...4b2f4eab9.jpeg https://cimg7.ibsrv.net/gimg/www.off...80b6dd05b.jpeg Thanks |
So did it work?

Chris Is it the yellow cable (from the Livorsi tac gauge) and the blue small cable (from the Garmin GPS) I must connect? Then configure the gps to nmea 0183? |

Chris ”Serial port 1 and 2” - ”NMEA standard”? And is there something special I must configure in the ”NMEA 0183 setup”? |
I am not familiar with 0183 wiring as The ones I have delt with run into a junction/geatway box that transfers the data into NMEA 2000 Data.. The Garmin is capable of reading 0183 data. Just have it turned on in the Menu This thread may help you though.

Also this has some wiring diagrams
https://www.offshoreonly.com/forums/...uestion-3.html I did see a couple places that with that setup you need the Baud Rate in the Garmin set to 4800 Chris |

https://www.offshoreonly.com/forums/...uestion-3.html I did see a couple places that with that setup you need the Baud Rate in the Garmin set to 4800 Chris I read those threads about wiring, but people say you must connect the blue Garmin cable to ”orange signal cable” or to the ”S” terminal on the Livorsi Speedo gauge. I dont have any of those. I just have the yellow ”nmea 0183” and the pink ”analog” cable that goes from the Livorsi tac gauge. According from Livorsi, if I have the Livorsi antenna. The white cable from the antenna should be connected to the yellow ”nmea 0183” cable from the Livorsi tac gauge. And the red and black cable should connect to the harness on the Livorsi speedo gauge. https://cimg9.ibsrv.net/gimg/www.off...f43a1b8bd9.png The Baude-rate 4800 in the Garmin GPS settings is, after I Google searched after it, ”nmea standard” i think. ”NMEA 0183 can be used in two different varieties for Garmin applications. NMEA Standard is the normally used language. This is the NMEA 0183 information sent at a 4800 baud rate. This baud rate is for autopilots, VHF radios, Sounder information, and compass input.” |
After looking at the Garmin wiring instructions I think this is the right wiring. The blue cable connects to the yellow ”nmea 0183” cable on the Livorsi tac gauge. And use the same ground for the Garmin and the Livorsi speedo gauge..? https://cimg4.ibsrv.net/gimg/www.off...04d3e98cc.jpeg |
|
And the ground from the Garmin GPS should be connected to the Livorsi Speedo ”ground” I think. https://cimg2.ibsrv.net/gimg/www.off...669bb2095.jpeg |
The Ground for all the gauges is usually Daisy chained to single solid ground on the fuse block at the helm. I would think the GPS and Gauges are all wired to that but make sure Also did some digging and confirmed the Livorsi can only accept data at 4800 Baud Rate. So find that setting and make sure its at 4800.

Chris The blue cable from the Garmin is a 0183 (TX+) output. And should be connected to the yellow ”NMEA 0183” wire from the Livorsi tach gauge. I connected those cables together + connected the GPS and Livorsi gauge cables to the same ground. Then I changed the settings in the Garmin GPS to ”NMEA standard” which should be the same as 4800 baud rate. I also made sure the transmitted sentence - GPRMC was turned on in the NMEA 0183 settings. I also got information from Livorsi to make sure the settings in the tach gauge is right. ”You have to go into the tach LCD screen and go into the Main Menu and go to Set Up. Then go to A/D Inputs and select A/D input 2 which is for GPS speed and turn that on.” I didnt get any satellite connection because my boat is located inside so I cant tell if it works yet. But I will tell if it works when the Garmin can find a satellite connection. |
Did you manage to make this work?
There is an old, dead, Livorsi GPS speedometer for the rear seat passengers in my Skater, and I am toying with the idea of resurrecting it by connecting it to a Garmin 720. |
Never mind
Never mind.
I just ordered 2 SmartCraft speedos. |
Curious if anyone has any advice for my wiring. I have a Garmin 741 XS and a Livorsi GPS speedo, Garmin works great but cant get the speedo to work. I have the blue wire from the Garmin hooked to the white wire from the speedo and when turning the GPS on the speedo cycles, goes to the 9 oclock position and after GPS signal is required speedo goes to zero or jumps to around 4 mph and will not read speed? I do not see where i can change the output settings on the GPS, I have the same setup as this thread starter and do not see a solution in this string. Anybody know what I'm doing wrong?

I doubt you can make it work.
NMEA0183 is a mess. See the thread I created about hooking up a newer Garmin GPS to Mercury Smartcraft. |

Are you dealing with the Livorsi antenna that died because of the non-replaceable battery?
If so, just remove it and replace it with this: |
wieland, does the back of your speedo look like this ? which white wire are you using
https://cimg7.ibsrv.net/gimg/www.off...a6fcd98252.jpg |
Yes, exactly. I had an older Garmin GPS 180 that I had prior hooked to the speedo and it worked perfectly. The new 741 XS i wired the same way, blue wire from Garmin to white wire from speedo and it doesn't work.
|
My old one was a 180 also, are you using the white wire in the big plug or the single small one........
|
the single small one you have labeled PRT
|
ok thats the way Im connected, I did go into settings and turned on 2 other perimeters that were off

Get an NMEA2000 speedometer. |
