Ted,

We have not run the sprayer other than to calibrate it yesterday.  This is the new Nav2 that I had to send to AgExpress.  They did not find any problems with it, but recalibrated it and flashed the firmware.  It came back with 4.51 loaded.  I will recheck the system this afternoon.  I know we had it set to use GPS speed and it was showing speed when I did the calibration.  I will double check that the speed has not been  changed back to radar.
