Installing The Navigation System

Important: There may be installation variations among different navigation systems, and some instructions may be vehicle-specific. Read and follow the product wiring instructions and consult our vehicle manual for your car's harness connections.

Steps:

• Splice and solder the navigation system wires into the car's harness as we did earlier. The red wire connects to the positive 12-volt power wire to our car's battery and the brown wire connects to the negative battery pole wire. The white and yellow wire connect to the reverse signal of the back-up lights and the purple wire connects to the accessory signal. Go back and solder the connections.

• Weekend Mechanic Pro Tip: Though it's not necessary to solder wire connections in this case, it's a good practice that will prevent wiring trouble later on. Again, it's important to tape up the wiring connections and secure them with wire ties.

• To get access to the speed sensor connection behind the radio, remove the shifter console and the radio trim and unscrews and removes the radio. Many cars have a speedometer signal VSS wire on one of the radio connections. The speed sensor or VSS harness is fed up to the radio compartment. Check the wires for the correct connection.

• The antenna pad is installed into the radio compartment where it will be hidden, and the antenna wire is fed down to the interior.

• Then the navigation display cable is connected to our high-tech mirror--installed earlier--and the cable is tucked into the interior trim and fed down the A-pillar.

• Splice and solder the VSS wire into the selected radio harness wire as done earlier, and secure it with tape and a wire tie.

• The radio can now be re-installed.
  
  
• The FM antenna tape is adhered to the window and the antenna amplifier is secured to the middle of the strip. With the front passenger seat removed, install the navigation unit using hook and loop tape to secure it to the carpet.

• The TMC module is also secured to the carpet. These units can be located in other areas if there's not enough room under the seat.

• Run the cables and harnesses under the carpet (figure G) and make the connections to the navigation unit. The only thing left to do is to tuck away and secure the wires and clean the area up.

• Finally the seat is re-installed leaving easy access to the navigation CD unit.
