OEM Japanese navigation wanted
 

Hello
I'm in japan and have a 2004 525i
Sadly my navigation system doesn't work

I've tried everything and many have suggested ways to repair it, but now I just want to get another and replace it

If someone has a Japanese navigation system they don't want anymore because they have replaced it please Let me know

Looking forward to hearing from someone and get mine working

Thanks

What is wrong with the navigation system?

I just fixed mine that had a DVD disc read problem.

In my screen my position never changes just the arrow for the direction

So the arrow just spins around
Also it shows me in the ocean always
I connected a new GPS receiver and still nothing changes

Have you checked errors such as speed sensor?

You are primarily to check for errors.

Japanese DVD navigation can be ported from other cars.

Alternatively, it can be replaced with E60 or E90 HDD navigation (CE2).

Hi thanks for your suggestion

I check and found some fault codes
The first was

A3EC no wheel speed sensor

Do you know where or which one it refers too?

A3EC is that the vehicle speed signal is not input to the DVD navigation on the trunk.

You should check the wiring.

This will be a hint.

So recently a signal is sometimes being sent to the navigation and I can actually get motion or movement on my screen

So I will replace all the wires from the rear navigation DVD in the boot to the front of the car

Doing this will at least eliminate any broken wires that maybe caused my the problem making the navigation work sometimes

I will keep everyone updated through the process to see if it fixes the problem
