Hello Everybody. I've tried searching for a thread that might cover this topic, but i was unsuccessful.

My girlfirend just purchased an 2004 X5, 3.0i that was set up to have a navigation system. The issue, is that she unknowingly went through the purchase without checking the navigation system ( i know, i know...), and when I checked it out, I found out that she is missing the navigation module in the back and the cd changer, and it seems like who ever took them out, cut the wires to do so.


Current Issues:

1. I'm trying to find out what is the best way to fix those cut wires (the nav unit and cd changer)

2. Once I try to purchase a MK4 unit, what are the most important things I should make sure (compatability wise) to check for so that I don't buy the wrong unit.

I will try to upload pictures in the next 24 hours. Thanks for the help.

That stinks, but it is fix-able...

You can buy the replacement plugs from BMW. Or, it might be easier to get a navigation harness, and then just cut the plugs off an existing harness and splice the wires together. Then, you would just have to match wire colors to put it back together.

Thanks Brian-BMW. Do you know where I can purchase the navigation harness?

Sounds like the nav got stolen.

Go to a wreckers and cut the necessary connectors of a wiring loom. Make sure you have more than enough cable slack so you can make a good cable join in comfort.
To join the wires, join them colour-for-colour by soldering and then fitting heatshrink tubing.
Of course, you need to slide the heatshrink onto the wire before you join it, and the heat shrink needs to be far enough down the wire so it won't shrink when soldering. Hence you need som good 10 inches of cable slack.


Just make sure it is a working Mk4. Some older units are getting weak lasers these days. As for OS software you can always load the latest software (4-1/100).

To code or program the nav, you can either use a dealer ofr use my NavCoder software. If the dealer charges for coding, you may find using NavCoder is cheaper - especially if you can find a friendly forum member in your neighbourhood who has NavCoder and can do it for you.

Thanks Kiwijochen! I will look into where the wreckers are here in my city. In regards to coding or programming the nav, if I can obtain the Navcoder software, is it as easy as poping the disc in?

I will update once I look into the wreckers.

I'm looking around for an MK4, and I came across this on ebay. Would this be okay? I noticed that the seller is also including two cables, a blue and red one. Those are the connecting harnesses I need right?

That's one of the oldest MKIV units (like mine), early P/N. Those look like the plugs that go to it. To bad someone cut the wires instead of pulling the whole harnass.

NavCoder runs on a laptop.

You connect the laptop to the car's ibus with a homemade interface or one purchased from www.reslers.de
