Russ, drop me an email if you find that it CAN be retrofitted. Would like to get into a GPS_yield monitor system and would prefer to use Fieldstar. The other Russ in Iowa rubrandt@yahoo.com
yes, all that been done - at first making the adjustments worked but now they fail to do anything - mechanic says the only recourse - is to replace. I can't believe it would last a couple years.
