In 2010, some dash-mounted GPS navigation units allow you to view reverse camera footage on the display before activating the navigation system. If you don't have this feature, you can still view this footage, but you'll have to buy a specialized display and camera transmitter. The back-up camera made by Peak is one of those models. Retailing just over $100 in December 2010, depending on whether you chose the 2.4-inch, 3.5-inch or 7-inch monitor, this camera and dashboard display configuration eliminate the need for help from your GPS receiver.
Attach your Peak dashboard monitor to the windshield by firmly pressing its suction-cup mount to the glass.
Plug the monitor's power into your cigarette lighter, and charge it.
Remove your license plate using either a screwdriver or wrench. Feed the reverse camera's wiring through any hole behind the plate that gains you access to the interior of the car. If no hole exists, drill a 1/2-inch hole carefully into the trunk. Feed the camera wire through. Return the license plate, then attach the back-up camera with the two top bolts, with all the wiring inside the trunk. (If you don't have a trunk, you'll have to route your wire a little more ingeniously toward one of the taillight assemblies.)
Disconnect the vehicle battery cables, negative wire first, using a wrench. Have someone press the brake pedal before you do this, so you can verify which light assembly you'll need to access. Attach the back-up camera's power cord to one of the two rear taillights. Feed your wire along the bottom of your trunk to the rear light assembly. A compatible port can often be found into which you can plug the power cord. Otherwise, connect the positive and negative leads of the power wire to the appropriate ports in the back of your taillight assembly. Use a screwdriver and Peak's wire splicing kit that comes with the unit.
Route your remaining wire from the taillight to a spot inside the trunk where you can entry into the backseat area. A rear speaker often offers the best path, but you can drill another hole inconspicuously if necessary. Mount the transmitter nearby using two-sided Velcro tape. Plug the transmitter in, reconnect your battery posts (positive first, then negative) and turn your monitor on to test your reverse camera system.
