Thank you so much for that help, would have never thought to look there. I suppose they need to update the instructions sent with the AFS cable. Since you seem to know something aobut these systems i have another question. When our combine was delivered it had the display, and yield monitors installed with the 16MB ata memory card. They handed me the empty box the screen came in and taht was that. do i have to purchase the scandisk memory card reader and the software to make the maps separatelyIJ Seems like for $4000 they should throw that in. If you or someone that knows this stuff would please email me or post the info on here, i would greatly appreciate it. big_al_jack@yahoo.com
