My camera decided to die so I don’t have any pictures. If I can get the camera to come back to life I will post pictures of all of these steps.

First the Bluetooth bypass. If you have the VAIS technology SL2Vi installed you will be able to get video in motion. You will also be able to get ipod to work including the folders in motion.

Step 1: remove the head unit. The forum is full of instruction on this. Use the search button and you will find several DIYs on this. If you have questions about this please send me a pm and I can try to explain further.

Step 2: once you have the head unit removed. Now remove the screen. There are 2 bolts under the screen where the head unit use to be. Once you remove these 2 bolts. The screen will pull forward. No need to take it out all the way. You are only interested in the 1 plug on the back. This is the plug nearest to the driver side. It is white plug with several wires. It is listed as 26 pin connector but has lot fewer wires than that. If you count the number of pins it should have 26 pins.

Remove the plug. The wire that you are interested in is red wire in the middle of the plug. Be careful there is another red wire on the same plug but it is toward the end. You don’t want to cut the red wire toward the end. See the picture of the plug M5 below. Tape both ends of the cut wire so there is no chance for the wires to touch any thing. Now cut the white wire at pin number 8. tie the plug side of this wire to pin number 1 (white wire with black stripe). tape the body side of the wire so no chance of short.

Step 3: Put everything back together. This should free up the Bluetooth and ipod.

Now the Navigation hack during motion

This is little more complicated process. Just to give little background. I originally built a little pulse generator to fool the navigation system. It worked well but problem was that the actual pulse voltage was changing in the original system but my pulse generator was only producing fixed voltage since I was not looking at the speed of the car. So I had to abandon this method and had to go to a switch set up. They way it works now is that when I need to input an address I have to hit a switch. Once I am done with the input I have to turn the switch back on. This may be too much pain for some people but for me that is all I could come up with for now. I may change the setup in the future but for now it is working well. So below are the steps.

Step 1: remove the tool tray out of the luggage compartment. This is easy; just open the door to expose the tool tray. Lift the back of the tool tray and pull it toward the back of the car. It should slide out. Once the tool tray is out you should see a DVD player on the passenger side.
Step 2: unplug the large white plug on the back of the DVD player. The plug that you are interested in is the largest plug on the back of the DVD player. This is 24 pin connector. There is only one wire that you are interested in. it is brown wire located at pin number 4. There is only one brown wire so it should be easy to identify.See the picture below for the N3 Plug.

Step 3: cut the brown wire. Make sure to leave enough wire on both sides to splice in the new wire that you are going to run to the front of the car next to driver side.

Step 4: take 2 wires, each 20 foot long. Connect one wire to the plug side of the brown wire that was cut in the step 3 above. Connect the 2nd wire to the body side of the brown wire that was cut in step 3.

Step 5: rune the 2 wires to the front of the car on the driver side. This is fairly easy. I put my wires under the door scuff plates. The scuff plates can be pulled up easily. These are held in with clips only.

Step 6: run the wires to where you are going to install the switch. You can get “ON” and “OFF” switch from local radio shack or auto parts store. Here is the link to the switch that I used. http://www.radioshack.com/product/in...entPage=search

Install the switch and land the wires on to the switch.

When the switch is in position “1” the system works just like it would be from factory. When you want to input the address into navigation while moving just flip the switch in position “O”. This will cut the speed signal to the navigation ECU. So the ECU thinks that the car is stopped and all of the buttons are released. Once you are done with the entry, flip the switch back and everything should be back to normal. If you forget to flip the switch back the Nav system will be choppy.

I did this stuff 2 weeks ago. Every thing is working so far without any issues.

Good luck
