What do I need to gather yield data on a 5088 with a pro 600? I have a ezguide 500 and a 372 receiver used on other tractors. What will it take to get a gps signal for the 600? Also the 600 uses a data card, are they exclusive to CIH or are there other options? What about getting the data card info onto a computer and then printing out maps? Is that a CIH program? Lot of ??? here. Thanks for any insight.
