Near Intersection of I-35 & I-90 Southern Mn. | I'm unsure what to suggest, it could be some confusion within the PF 3000 itself. I used to be fairly knowledgeable on them but its been a while. I believe they needed to have a working memory card before GPS was even attempted since the PF3000 could be used without GPS and point by point logging. The unit just gave load and field totals when operated that way. |
