Can anyone advise on a suitable AIS system that will both transmit and receive and be able to integrate with a Raymarine C70 (2007 year).

The C70 is located at the binnacle but I have a Seatalk Interface Box close to the chart table and an ICOM M423 also at the chart table so not sure whether the antenna feed can come from this or not?

Any help would be appreciated.

Any AIS system will interface with a C70. Depending on what else you have connected to the C70, you may need a multiplexer.
 
If you have a classic C then if you are transmitting 0183 at normal speed to anything like a DSC you will have problems. Setting the baud rate for the high speed required by most AIS engines will mean that high speed is all you will get both in and out. I have overcome this issue on three classic C series / AIS installs without a multiplexer by using the Garmin AIS, it has the facility to use low speed 0183, it does not refresh quite as quickly but it does function. If you do use the Garmin then I suggest you buy one red and one green "aeroplane" safety switches, green cover for turning transmit on and off and the red safety cover for the auto pan pan transmit.

The C70 has an NMEA socket - it's the bottom right as you look at the back panel. If there's nothing plugged into this, then all you need to do is plug the AIS in and possibly set the port to high speed. However, unless you kept the plug that came with the plotter in a safe place, you will find that they are not easily available. I've just had to make my own, using some crimp-on socket contacts and hot-melt glue.

I too have a C70 classic and the limitation of it is that there is only one NMEA port.
If it's used for AIS the port speed needs setting to 38400 baud. That also means the output will
be 38400 baud and its unlikely your VHF will accept this higher speed data.
My solution was add another GPS sensor to provide a dedicated GPS feed for the VHF.

Fitting a multiplexer may be an alternative solution.

Check you have the latest C70 software, downloadable from Raymarine, as this improved AIS functionality.

One issue that remains is the the C70 does not show up AtoN's but otherwise I find it all works very well with AIS Receiver.

I think some posters missed the fact that you want to fit a transceiver. AIS transceivers have to have their own independent GPS receiver, and in almost all cases this can be used to provide GPS data for use by, for example, a DSC radio. So there isn't a problem.

Good point.
I am fitting a digital yacht AIT2000 with same aim, upgrading from previous DY receiver.
