As noted earlier you need a class B transponder. Depending on where you buy them they cost around $500 US (less other places).
Looked at your chart plotter and it does accept AIS data so no problem there.
You will also need either a dedicated VHF antenna
for the AIS or an antenna
splitter that lets you hook the AIS up to your current
VHF antenna (assuming you have a VHF).
SOme AIS manufacturers sell units with a built in antenna splitter. The AIS unit will have its own dedicated GPS
unit, which is necessary.
Hooking this up is fairly easy - but like everything on a boat will take you 3 times longer than you estimated
We have this one
not necessarily recommending it - but it works and we've had no problems in the 3 years we've had it. There are many many others out there
