To check for Y2K just see if you can scroll the date up to the year 2000. To add a different receiver you will plug it into a plug behind the panel outside the cab on the right side. We've been having some good results using $200 Garmin receivers for yield mapping. The card you need will be 1 mb SRAM cards. You can still get them from Envoy data. You can also get a card reader from them. The problems I have had with them is trying to read them in a laptop with anything newer than windows 98.
