Troubleshooting quick tips:

While the GPS-50-1 is operating, the dot in the upper left corner of the display will indicate the status. On steady

indicates it is powered up but not receiving any BIM bus activity. Flashing indicates it is communicating on the BIM bus.

A dot in the upper center indicates that it is receiving a valid GPS signal. A dot in the lower center indicates the

accelerometer is actively correcting the speedometer reading.

When the key is off the dot in the upper left corner will flash very slowly. If the switch on the GPS-50-1 is held, it will flash

rapidly indicating that the key is off.

To see the number of satellites being tracked, signal strength, speed, and heading on the GPS display, press and hold the

switch with the key on. It will toggle between displaying the number of satellites tracked followed by a dash (), the

signal strength followed by three dashes, current speed in km/h, and the heading in degrees.
