2007+ Altima Navigation Bypass

First I gathered all the tools and stuff I would need. The shopping list is as follows:

• A switch (Single Pole Single Throw, SPST)

· Wire (I used 20 gauge, but smaller wouldn't hurt, it looked like the wires were more along the lines of 24 gauge)

• Electrical tape or Wire Nuts (I went with wire nuts because it is faster and more reliable IMO)

The tools you will need:

• Wire snips (you have to strip a lot of wire, and trust me you don't want to do it by hand)
• Flat head screwdriver (...doesn't need to be anything specific)
• Phillips head screwdriver (I believe it was a PH1, but it could have been a PH2, either way it was a decent sized one)
• Cloth to keep from scratching everything while taking it apart.

How to get to the wires:
(** THIS IS DIFFERENT THAN THE BASIC BOSE UNIT, THERE ARE MORE STEPS! **)

1. Remove the bottom cover:



All this takes is a little prying near the back of the panel (the end closest to the front of the car).
It will come, but be careful.

2. Remove the fascia piece around the CD changer. All you do is pull carefully around the top and wiggle it out, it should just pop right out.


*NOTE: I did this install from the passenger seat, and was able to just let this piece dangle while I did the install.

3. Next you should remove the A/C vents. The vents come out with a little bit of encouragement. You do this by placing a cloth in the seam and using the flathead screwdriver to carefully pry each side loose. The best I can tell you is to pry about an inch above the bottom that is where it worked for me.





4. Now you access to the myriad of screws you have to remove. First start by removing the two gold screws on the bottom (yes, doing this first is better).



5. Now you have to remove 6 screws. The first 4 that you remove are the one's that hold the CD Changer in place. The other two (of the first four) are next to those screws and hold a bracket in place that has to be taken out. The 4 pictured below are the first that you should remove, and the other two are located below the changer.



6. Now that you have taken those screws out you have to loosen (don't remove, they are a pain to get back) the two screws that hold the bracket that I mentioned in. The screws are squeezed between the CD Changer bracket and the side of the hold. Loosen these about 3 full turns and you should be good.

7. The last of the screws come out now, the two gold screws holding in the top of the changer. You can see them in the second picture of the A/C vents being removed.

8. Now you can pull the whole thing forward. Unrealspeed was right, you just have to pull... it won't break, but you should be careful.

9. Now that you have pulled the entire unit forward you can disconnect the wire harness that you have to mess with. The harness is the one closest to the driver (it's about an inch and change wide, and white). It's a standard connector, so just make sure to push the tab when pulling it out.

10. Now, take a good look at the connector. I have put a picture below, as well as the diagram from the service manual. The thing to remember is that the diagram is backwards when you are looking at the connector from the front (like the picture).




11. You will be splicing the switch into wire 8. That is the slot 2nd from the left, on top as you look at it in the picture!

12. The next step is to find the wire and cut/strip it, it is the color of the severed wire in the picture below.



13. Now splice in the wire that you are going to run for the switch. You can see one of them is already done in the picture above. Once you are done, with this, put the tape covering it back together, and start buttoning the whole thing up.



Where you put the switch is up to you, I still haven't figured out where to put it, but I want to make it look professional, so it might take me a few days to figure out the placement, and grow some to cut into my new car!
Here is it's temporary location:



** OH! I almost forgot. I didn't do this, but it would have been a huge help. I would do this on a flat surface and put the car in "N" and put the parking brake on. Some of the stuff gets in the way if you don't do this. But make sure that the car is off when doing this!!!

One thing that I noticed right away is that because this is the speed sensor. When you break the connection, it doesn't think you are moving, so it doesn't update the GPS map. Once you turn the switch on again, it takes it a minute to update where you are, and if you do it for too long, it might be COMPLETELY off for a while.
