Start by removing the shift knob. On the automatic there is a small plastic trim piece at the base of the knob. Gently pull stright down on this and it will pop off. Next, remove the retaining clip that resides under the plastic trim piece. With the retaining clip removed the knob will come off by pulling up on it.
Once the knob is removed you can remove the trim panel that surrounds the shifter by pulling up on it - there are no screws, just clips holding it in place. I found it was easiest to put my fingers down inside the hole where the shifter comes through and grip the bottom of the panel. There are two harnesses that must be disconnected once the panel pops out. The trim piece around the screen can then be pulled stright out (I don't remember there being any screws holding it in).
With the first trim piece out you can remove two screws that hold the radio face in place. With the two screws removed the radio face will pull out, bottom first. There are two tabs on the top of the plate, but other then that it comes right out.
Now that the trim pieces have been removed you can see the main control unit - it is a big shiney box immediately behind the radio face. There are four screws holding it in - 2 underneath it and two above it that also hold the screen in place. When you remove all the screws the screen will have to be pulled out also, as its mounting backets rest on top of the control units mounting brackets.
After the unit is pulled out it really helps if there is somebody else to assist removing all the plugs. It seems like there are 20-25 plugs that have to be disconnected! (In reality there are probably 8 or so). All the plugs are unique so you don't have to worry about plugging anything back in wrong.
NOTE: With this unit unplugged do NOT turn the ignition power on. It may even be a good idea to disconnect the negative cable to the battery, although I didn't.
OK, now that everything is apart remove the navigation controls from the trim piece and also remove the back panel of the control panel to expose the circuit board. There are two wires that must be soldered -
With the two wires soldered on you can route them through the opening on the back panel of the control panel and put the control panel back together and back in the screen trim piece.
The last installation step is to wire up the module. Naturally, the two wires that we just soldered to the control panel must be connected to the same wires on the module (black and red twisted pair).
The main module has 6 wires on it:
Twisted Red - To "OK" button
Twisted Black - To "OK" button
Yellow (fused) - To switched igntion (Purple)
Black - To ground (Black)
Green - (-) to VSS Bypass relay (Pin 85 of included relay)
Purple - Reverse input (Only needed if OEM back up camera is present, orange)
The included relay has 5 wires on it, identified by pin numbers (remove the relay from the socket to view the pin numbers)
Pin 85 - To KPtechnologies VSS output (Green)
Pin 86 - To switched ignition (Purple)
Pin 30 - To one side of VSS Wire (Gray) (VSS wire must be cut)
Pin 87A - To other side of VSS Wire (Gray) (VSS wire must be cut)
Pin 87 - Not used
In the pictures you can see the relay Pin 86 wires with the yellow wire of the KPtech module. You can also see the gray wire in the OEM harness that has been cut to allow the VSS bypass to function (program while moving). Lastly, you can see the connection for ground for the module.
Now that the unit is wired up plug all the harnesses back in to the radio control unit BEFORE testing the unit. ***** IF YOU TURN THE IGNITION ON WHILE THE UNIT IS UNPLUGGED YOU WILL TRIP EVERY CAUTION LIGHT ON THE DASH WHICH MAY REQUIRE A TRIP TO THE DEALER ***** I learned this the hard way, but we were able to reset every light after about 60 mintues of messing with different reset procedures. The second install I did, I did NOT turn the igntion on but the air bag light still came on - this can be reset with a simple procedure of turning the ignition on, waiting for the air bag light to shut off, then within 1 second turning the ignition back off (repeat this 4 times).
It can be a bit tricky getting everything back together before testing, as you will need access to the module for tuning the "OK" delay time. I was able to place the unit behind the dash to the passengers side of the radio control unit - there is a pocket there just big enough for the module.
To enable the VSS Bypass mode you must press the "OK" button and hold it down for at least 2 seconds. Once you release the button you should be able to hear the relay click. With the relay energized you should have full access to programming the navigation unit as if you were sitting still
NOTE - As a safety precaution video will still NOT be able to be displayed on the screen.
