DR Cable Wiring

Cable Wiring
The Dead Reckoning (DR) cable is used by the 7500
to provide dead reckoning, which allows the 7500 to
continue to get navigation guidance even if it loses GPS
reception. The DR cable is also needed for both the 7200
and 7500 to use a backup camera. The DR cable must be
installed to the Reverse Light Switch. For information
about configuring the backup camera, see
The DR cable connections must be installed by a
garmin-authorized, licensed installer.
Warning: The terms of the Garmin Warranty
require that the DR (Dead Reckoning) cable with
bare wire leads be installed by Garmin-authorized,
licensed installers.
