My vessel view / mph and fuel range recently stopped working. I was also told that my GPS antenna needed replaced. Are these possibly tied together independent issues? Boat is an 07, 48 Sundancer with Cummins diesels.

Very likely they are related. Unless your boat has an independent depth sounder with speed sensor (which is uncommon), the VesselView needs to get its speed data from the installed electronics. Unless your systems have been updated from original, the VV input is going to be via NMEA 0183. If your GPS is shot, you shouldn't be seeing speed on your MFD unless you have a separate speed sensor that measures speed through the water (STW) such as a paddle wheel transducer on the hull. GPS measures speed over the ground (SOG) by comparing sequential positions.My vessel view / mph and fuel range recently stopped working. I was also told that my GPS antenna needed replaced.

Which VV do you have? If original vintage, it should have a NMEA 0183 input. The interface is one-way only, older VV are listen only. Newer VV usually are NMEA 2000 capable and will send and receive.Following. My VV has no GPS in put either. Nothing in the VV manual about networking it. All of the Raymarine stuff talks amongst themselves via Ethernet.
It’s a 1.5. I see 2 plugs on the back of it that look like they go to the 6 way splitter. Just got the boat and it’s never worked, but all electronics work.Which VV do you have?

Should be NMEA 0183 input-only capable. The interface is typically via a pigtail on the harness from the J-box (splitter) to the VV. There should be a number of those offshoots from the harness for things like the gauges, ambient air temp sensor, etc.It’s a 1.5.

Is it on the splitter end or the VV end?Should be NMEA 0183 input-only capable. The interface is typically via a pigtail on the harness from the J-box (splitter) to the VV. There should be a number of those offshoots from the harness for things like the gauges, ambient air temp sensor, etc.
The pigtails start to split off from the main harness just downstream (toward the VV) of the plugs coming out of the splitter (J-Box). There are usually several, likely bound together with ties and/or tape. I've got my old harness and will try to dig it out tonight and provide picures.Is it on the splitter end or the VV end?
That would be great. I appreciate that. Thanks so much.The pigtails start to split off from the main harness just downstream (toward the VV) of the plugs coming out of the splitter (J-Box).

Three photos attached. One is the overall harness, then one of the NMEA cable connector, then one of the two wire leads.That would be great. I appreciate that. Thanks so much.
The DSM should interface with the SeatalkHS ethernet router; each of your E120's should also. The wiring and connectors are Ethernet style like on your home network.Thanks very much for this. I also have no nav or depth data on the VV. I don’t think I have a multiplexer. The DSM-300 sounder, both E-120’s and I think the AP all plug in to the seatalk hub. I’m wondering if the multiplexer failed and they just installed a seatalk hub to get the Ray stuff communicating. That would have taken the VV out of the loop.
If that’s the case I should be able to go 0183 out of the master E-120 and into the VV. I’ll poke around under the dash when I get some down time.
Thanks again. This was a huge help.
BTW as an edit - if the SeatalkHS router isn't working then there will be no data exchanged between the two E120 displays. One (the slave) will be void of any data.The DSM should interface with the SeatalkHS ethernet router; each of your E120's should also. The wiring and connectors are Ethernet style like on your home network.
The SmartPilot course computer does not interface with SeatalkHS ethernet, it interfaces with Seatalk1 and NMEA0183.
If the Comm LED's on the SeatalkHS router are not blinking showing communication when the MFD's and DSM are powered up then you can swap a standard home ethernet router in it's place to test and see if the Ray one is not functioning.
Here is a picture I put together years ago showing how the Seatalk1 is interfaced with the SmartPilot.
The GPS if original Raymarine should interface with the NMEA input and output on the course computer; the white, blue, red, and black wires on the NMEA terminals.

So, you're not getting a depth signal, could be your transducer failed (not uncommon) or it's not connected. Since you are getting fixes, looks like your GPS is working. As to course, with GPS operating you should be able to see Course over Ground (COG). I imagine that screen is set to show the heading sensor course but I think you should be able to show COG through settings.Thanks. I’ll check for the green and white wires. Something else a little off. Notice the upper left corner. Course and depth are zero.
