Hello, my first post. Forgive if this has been posted elsewhere but I have searched high and low but I have found nothing that fits my set-up.
SH suggest the 2400’s blue Rx to Garmin’s brown Rx. I have tried changing the SH data speed to 38400. I cannot find anything to change on the Garmin.


I’m pretty ancient and electronics are not my best subject, so if any of you kind people can help I would be very grateful.
 
After another frustrating day, I finally called Garmin who confirmed that the UHD2 75CV version will not display AIS targets.
 
That is strange as AIS is mentioned on pages 21 & 22 19 to 22 of your user manual and shows the symbology that would be shown.

I went and had a look to see as I have the older UHD 95SV where the same info is mentioned on page 19 of my manual.

reading your first post again you mention connecting the Rx to the Rx, would you not connect the Tx of the SH GX2400 to the Rx of the Garmin?
I have not looked at the SH GX2400 manual so maybe talking out my hat here :)

Edit: Have you connected it and set it up via NMEA 2000? you mention 0183 in the title, the Garmin is NMEA2000 only

Alicat, thank you for your reply.
Rx to Rx, yes a good point , I’ll check. I’m not familiar with NMEA, I have never had a boat with this before.
The online manual does mention 0183 page 105.
The web page I posted for the set up: MENU -other vessels; does not exist on my Echomap
I spent quite a while on the phone to Garmin and the agent discovered that UHD 2 CV does not support AIS, whereas the UHD CV does. I think he said that the UHD 2 models have to be SV not CV. So if you want AIS buy the older UHD or the much more expensive UHD 2 SV.
I might try the NMEA 2000 just to make sure as I really wanted AIS displayed, any ideas what wire goes where please?

NMEA 2000 is plug and play. NMEA 0183 is bare wires. Your model does not have 0183 and it doesn't support AIS according to the manuals. A rather disappointing model in my opinion. I would complain very loudly about the lack of AIS support, it's a basic thing these days.
 
Yes I agree a disappointing model, effectively downgraded from the UHD model. I have spoken with Garmin, all they suggest is that I return it, easier said than done. It is all installed, probably the mounting screw holes are marked, the power cable has been cut to length and I have purchased a sunscreen and quick release mount from other suppliers.


There is no manual for the UHD 2 as far as I’m aware and no notification that this unit does not support NMEA. Puts me off buying Garmin in the future.

Specification here: Garmin ECHOMAP™ UHD2 7″ cv | Chartplotters

Somewhat vague. i would be very disappointed in the lack of AIS display and would return it as unfit for purpose. I like Garmin, but this is a poor show.

Manuals are here : ECHOMAP™ UHD2 7" Keyed Chartplotters | Garmin Support

I guess I got my course crossed, I went to the US support site and it just gave me the manual for the SV model though it says for the UHD2 6X/7X/9X and no mention of the CV or SV models, joys of living in the EU when you want something in English you get steered to the US rather than UK sites.

My UHD 95SV has both 0183 and 2000 flavours of NMEA

I tried hard to return it but the very well known mail order company in Portsmouth would not accept it as it had been fitted and used albeit for just 5 minutes. Pretty poor customer service. Lesson learned to make absolutely sure your proposed purchase performs as you want before ordering. Garmin would not help either.

If you paid for it by credit card, might be worth contacting them ?
 
That Standard Horizon (Yaesu) looks like a good option for what I want, just awaiting my SRC certificate coming from the RYA and trying to figure my way around the rules here in Belgium as everything seems to need a separate licence for the boat.
Plus we have new regulations that came into force on 1st Jan 2023 and I can see no reference to VDES in any information about marine radios complying with it.

From 1 January 2023, the VDES (VHF Data Exchange System, the new channel plan that introduces digital channels) will be put into operation.

As a result, between January 1, 2023 and December 31, 2023, EVERY VHF radio must be programmed according to this new frequency plan.

I'm going to say it as it is. The specs/user manual can be found in 20 seconds on Garmin's website showing exactly which NMEA0183 sentences it will receive, and this clearly shows it will not receive AIS data via NMEA0183. You bought a base-level unit and should expect that it doesn't do everything, increasing the onus on you to check, and it takes a mere 20 seconds to check, on a very good website.

A mistake was made here, but it was made by you not by Garmin. You should accept your own mistakes, and not disparage others ("pretty poor customer service") who have done nothing wrong. "Lesson learned...make...sure...before ordering" - really? You didn't already know that?

In my defence, I discussed the capabilities with a store assistant, he told me that the unit would display AIS. He too was thinking the UHD 2 was superior to the UHD, understandable logic.


I joined this forum for friendly advice and knowledge which I have received however, I don’t need to be berated by you with your condescending remarks so I will make this my last post.

Paul, you are linking to the manual for a higher spec Garmin unit, not the one under discussion here.

The older UHD CV seems to be the higher spec here compared with the UHD2 CV

What a cry baby. You made a mistake, then blamed and disparaged others. I call out that behaviour, and you go off and cry. Grow up and accept the mistake you made. You will get tons of friendly advice on knowledge on here if you wish, but you won't get universal support for your behaviour in this instance.

Regarding your first para, I fear you might be misunderstanding what "display AIS" means. That you got a promise from a store attendant is new information, but if his/her information was as you have stated it then that information correct. Both Garmin units under discussion here (UHD and UHD2) will display AIS. They just won't display AIS when the data input is by (defunct) NMEA0183. They need the AIS data input to come from N2k. That is clearly set out in the online manuals which are are very accessible on Garmin's excellent website.
