Can I use a WatchMate-850, XB-8000 or WatchMate Vision with my classic E80 or E120?
Yes. Just connect them via NMEA 0183. If your Raymarine is older than about 2006 you may need to update the firmware in it. Check the manual to see if yours has AIS support. If not, here's a link to download the Raymarine firmware: http://www.raymarine.com/knowledgebase/index.cfm?view=3753
