I can't seem to get the AIS/GPS of the Furuno to "ungray"...could this be because I need a heading sensor string on port 3? The need for this is NOT in the manual nor was it mentioned in the sales process. And as I have a steel boat, there's issues with placement of any fluxgate compass, which I wasn't going to get until I decided on an auto-pilot.

I might try to just add the SH VHF/AIS first to the NMEA input with everything else to see if the Ray will take it. If it doesn't then add the multiplexer. I don't think in either case the upgrade would hurt them, and more likely will help.Bill Bishop - Parmainhttps://www.blogger.com/profile/11554223870035485145noreply@blogger.comtag:blogger.com,1999:blog-7834826019588534175.post-36343742205633466622013-02-08T09:10:38.611-05:002013-02-08T09:10:38.611-05:00What is the latest on this issue?

I had the E120 with version 5.52, but since I'm actively cruising the Caribbean right now, I didn't even know about it.<br /><br />I read about this issue a few days ago while helping friends re-configure their E120 Classic network. They're getting magnetic heading info from their autopilot, but it's multiplexed together with speed/log/depth/wind from their Nexus 2 instruments at 4800b/s over NMEA-0183, so it's not true Fast Heading data at 10Hz. <br /><br />Since the new 5.69 software is supposed to address performance issues with AIS targets (they're also installing a new StdHoriz Matrix AIS VHF radio), I'd like them to upgrade, but that would require a NEMA multiplexer - and they're already in the middle of a "surprise" deck core replacement, so I'm loath to tell them they have to purchase more hardware. So I'm telling them to stay with v5.52 and the slower heading updates and see how the AIS data works.<br /><br />Boatts - Break Out Another Ten Thousand...Jonhttps://www.blogger.com/profile/04372134801193848607noreply@blogger.comtag:blogger.com,1999:blog-7834826019588534175.post-75220260009433665532012-08-04T11:38:03.628-04:002012-08-04T11:38:03.628-04:00Starting with the NUVI, only the higher end units ...Starting with the NUVI, only the higher end units have a compass that is used for walking and hiking navigation. What most Garmin car units do is to remember the orientation, so the next time you turn it on, it puts the orientation you stopped with as your current orientation. The usage of compasses in cars are somewhat problematic because of the amount of steel in the car.<br /><br />The $200 dollar heading sensor is a stand alone fluxgate sensor, that requires additional hardware to convert the data to something the chartplotter can use. Raymarine at several points in the past had a standalone heading sensor that output heading data in Seatalk, if my memory was correct. Ray is planning to reintroduce this product at some point again in the near future. I think at this point you are stuck. There is a possible scenario that backward migration in software might be possible if the unit is old enough, but I would not recommend trying it. The consequences could be severe for both the unit and your pocketbook. The best bang for the buck for a heading sensor I have found to date is the KVH 1000 which can be purchased online from Cascade GPS about $562. you might also haunt Ebay and the ilk for a used or remanufactured unit. Sorry, but I know it's not good or inexpensive news.Bill Bishop - Parmainhttps://www.blogger.com/profile/11554223870035485145noreply@blogger.comtag:blogger.com,1999:blog-7834826019588534175.post-21041307127173226222012-08-02T11:42:27.501-04:002012-08-02T11:42:27.501-04:00I just updated my older c-80 to 5.5 and lost my ov...I just updated my older c-80 to 5.5 and lost my over lay. Raymarine wants $200 for a heading sensor. Is there another sensor at a lower price that you would use? Also, do I need just the sensor or the sensor and teh control head? who is this installed.
