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. DR 2 - GREEN OK to cut or splice past limiter. DR 1 - ORANGE Do NOT cut or splice the cable between the limiter and plug. DR 1 DR 2 Attaching the Dead Reckoning Cable to the Vehicle Adapter (StreetPilot 2660 only) 1. Locate the DR connector on the side of the vehicle adapter. The connector is "keyed" with a large and small receptacle. 2. Mate the DR plug to the connector on the vehicle adapter and push the plug into the connector until fully seated.

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.
