Default Garmin 4208 and AIS class B

After reading a couple of threads on other sites where some Garmin chartplotter owners were having problems connecting to AIS class B units I decided to check with Garmin. The answer I received was:

Some early units did have problems receiving AIS signals. If you experience this problem and have verified the wiring and software updates, we may need to know the serial numbers of all three units. Unfortunately, Garmin devices will not support AIS (class B).

What the hell does this mean???

Has anyone installed a class B ais with Garmin chartplotters?

Reply to that message and ask for a confirmation. Somebody did a boo-boo.
Write "please confirm Garmin devices will not support AIS (class B). " in the subject line.

I had already sent a reply but did not enter it they way you have suggested. I will give them a couple of days to respond and then try your method maybe they will clear this issue up. Garmin has been pretty good to work with in the past. With 3 chartplotters less than a year old on board it is pretty healthy investment in Garmin and I would not be very happy if they will not support AIS class B when there operations manual page 40 indicates it will.

What bothers me is they have my information on file with the serial numbers. Why don't they tell me if I have early models and there is a problem. I perform the updates as soon as they are available.
Thanks

TYPO? I think they meant to say: Unfortunately, some Garmin devices will not support AIS (class B).

I wonder what they consider an early unit? Less than a year old?

Nauticast recommends a 420 ohm transistor. see link below


http://www.milltechmarine.com/images...artPlotter.pdf

Does any one know how garmin chartploters display the information. On the PC software programs they are displayed on the charts. from what I can tell garmin just lists there position.

Does any one know how they are displayed on a 545s?

The Garmin 545 is AIS capable and can display AIS targets on the screen. The 5 closest will also be displayed in a list. This functionality was added in software update v4.0. You can view this functionality by placing your 545 in the Simulation Mode.


https://buy.garmin.com/shop/store/downloadsDetails.jsp?id=3521&product=010-00601-00&cID=148&pID=8109

Refer to pages 28 and 20 of the 545's Owner's Manual on how to set the functionality up and set safe zones.

Thank's bluewater I have not updated my unit and my owners manual is the original.

it is going to be interesting if the class B transmitters catch on. It will make navigation in close quarters easier at least in theory if all vessels have these.

Latest response form Garmin.

"This is correct at the current present time the Garmin units will only work with Class A transponder."

I have replied to Garmin asking when a software update or a Garmin module of some type will be available to include Class B.

Thank you for contacting Garmin International. At this point in time there has been no mention in making our units compatible with class B AIS transponders. The only solution to this problem unfortunately would be to obtain a Class A AIS unit.

Well thank you very much Garmin! I was a big supporter of Garmin but now I can't wait for the local boat show to unload on the Garmin salesmen that told me that when AIS is approved by the FCC Garmin products will be compatible.

Don't you think it would be a good idea when Class B AIS could be the best development in marine safety since radar?
BTW..... Class A is about $7000 when Class B is about $750.

I think after the US Standard is agreed on by the FCC and USCG there will be many products that will hit the street instantly. Here's one from ICOM that will come in at $500 - $600.

Tom,
From everything I have read it has been approved and is being used in the U.S. already. Like you have proven with your videos the Garmin chart plotters can receive and display information from an AIS unit. The AIS units I have looked at along with the ones you provided receive both Class A+B and transmit your information on class B from the unit. What I do not understand is if the AIS unit is sending data to the chart plotter to be displayed why should there be a problem weather it was Class A or B. It is a data signal and Class B is less Data than Class A.

I tend to agree with Sandya. Someone at Garmin has there wires crossed.

AIS B was approved. Units are shipping from most manufacturers. I have received mine, an ACR AIS B. My boat is on the hard for the winter, but I'm going to rig up something to check this out. Since the AIS data is sent out in NMEA words whether its from an A or a B transceiver, I suspect that Garmin plotters will receive, and correctly interpret those NMEA words the two types have in common, probably position, course and speed. An AIS B target may be shown as an unknown target because the vessel name is sent in a different string. At least I hope that's the situation, because its likely that could be fixed with a firmware update. God only knows what that would cost the company, but I sincerely hope it happens.

However, after the Raymarine WAAS satellite change debacle, Garmin is due a similar cockup. They may have painted themselves into a corner. I hope not; AIS B is the most important improvement in collision prevention since the advent of radar on recreational vessels. Bar none.

not to jump in as Garmin's defender here, but they haven't had a software release yet that came after the new AIS-B standard went official. Granted, it still might not be on their next rollout of firmware, but once they can get their hands on a couple of different transponders (since hey don't make one themselves) they will more than likely roll it into their line. Remember, they were one of the first to support viewing of the AIS-A info across a good deal of their product line, including in some older products that were out of production. Expecting Garmin to have some code writer anxiously waiting in the corner to crank out some support of new AIS infrastructure is over the top. Granted, their reply to you sucked, and did show little inclination about what class B is the tech had, but I wouldn't read as dire and it will never work, just a, "this is what we know we work with (now)".

The below mentioned units are AIS Class A compatible which is required on most if not all commercial vessels. The AIS you have is a Class B which is not compatible with any Garmin units at this time. In order for AIS to work you must have a Class A AIS transponder on board and hooked up to the unit for this feature to work. I do apologize for any inconvenience that you may have been caused by this but there is nothing that we can do.

I had sent them a copy from there web site listing AIS chart plotters.

I hate to sound like I'm Garmin bashing but they have no defense here. There information clearly states AIS compatible. No where do they mention Class A only.

By saying there is nothing we can do indicates they are doing nothing and sounds like they have no intention to do anything. I realize Garmin is a very big company and there could be a code writer somewhere working on this and the product support would have no idea but it does not sound good.

Good news Latest report

I was informed earlier today that all Garmin GPS Chartplotter that are AIS compatible had software updates that made them function with the AIS class B series transponders. With the above being stated this means that now all Garmin AIS capable units will work with both class A and B AIS devices. As with all Garmin units we highly recommend that you update your unit’s software with the most recent software version that we have available. To find the most recent software version you may visit our website at http://www8.garmin.com/support/download.jsp

Code writer works quick! LOL
