Appendix

DR Cable Wiring - For Dealer Installation Only (StreetPilot 2660 only)

The StreetPilot 2660 includes Dead Reckoning (DR) cable connections that must be installed by a

Garmin-authorized licensed installer. The DR connection consists of a 2-wire harness that connects to the

VSS (Vehicle Speed Sensor) and Reverse Light Switch on the bare wire end, and connects to the StreetPilot’s

vehicle adapter on the 2-prong molded connector end.

The Orange DR 1 cable wire attaches to the VSS. The unit software option Odometer Wave Type must be set

to either Square Wave or Sine Wave. This can be determined either by contacting the vehicle manufacturer or

by using an oscilloscope. Square Wave is the most common type. Do not connect the DR Cable into the

vehicle speed sensor signal from the ABS control.

The Green DR 2 cable wire attaches to the Reverse Light Switch. The unit software option Reverse Light

Polarity must be set to either High or Low. Contact the vehicle manufacturer for polarity or check with a

voltmeter. Set to High (most common) if a positive, high voltage is detected when the reverse lights are

illuminated. Set to Low if no or a low voltage is detected when the reverse lights are illuminated.
