Near Intersection of I-35 & I-90 Southern Mn. | As you know, you need VTG (Velocity To Go is my memory trick) to get the arrow and speed to work properly on the PF3000 as well as other Ag Leader products.
As I remember it, Garmin has a SNCNFG program to configure the sensors. This is where you set the GGA and VTG ON. I assume you have done this. Sometimes when an update is performed these settings get changed. If a change is made usually all NEMA strings are turned ON which is bad for use with the PF3000 as it will overwhelm it with information.
I would try running the configuration program again to be certain that you have VTG set to ON. |
Garmin 16 GPS, no VTG
