New electronics on an older boat?

[Scallywag-l36]

I'm contemplating buying a H460 built in 2000, which has all the original Raytheon (pre Raymarine) stuff for depth, speed/log, wind and autohelm too.
No chartplotter fitted, so looking to get a modern Garmin touchscreen or Raymarine plotter fitted. Can this older stuff be linked up to modern chartplotters? What 'compatibility' should I be looking for? Radar is ancient and low power too (i know how it feels!) so will likely replace that with more up to date one over time. Any 'gotchas' I need to be aware of?
Cheers!

Those old guys all talk in NEMA so they can be linked.. Not quite so elegant as the latest and graeatest networked stuff, but it works..

I thought that this old stuff does NOT output NEMA but outputs SeaTalk. They do make a box that "should" translate the Seatalk to NEMA.

I would suggest that you take a look at new transducers and tie everything to a Ray Chartplotter. If you want individual instruments later they are easy to add on.

New Wind,Speed & Depth are around $1500 +/-.

The old Raytheon Radars are not compatible with the new chart plotters. I have one in my garage.

The old Raytheon units could listen to NEMA 0183, not the new 2000, and I think the new Garmins can output the "0183 sentences", so it should be able to communicate with the autopilot and it may be able to use the wind speed/direction for display.. The radar, as Dave says, probably cannot output to the chartplotter so until that part is upgraded, ya won't be able to overlay radar onto the chart.(unless it does have Seatalk..??) . you'll have to use its old display.. No real problems.. I don't know when the Raytheon/Raymarine guys started using Seatalk, but I think it was around the time those were built.. The manuals should have all that data, including how to change their language if necessary.. My old Raytheon Loran unit (1989) would output 0183 and could tell the autopilot and the AIS locations that they needed..
