Retro fit navi in BMW E39....HELP!
The folowing problems occurs; When everything is fitted the screen starts, radio works (BM24, volume settings are possible and tune to another station) with the logo === BMW ===. But the system doesn't start any further. When I unplug the MK3, I should get the interface of the TV-module. But that doesn't do a thing. The screen stays completely white, nothing happens. Even after a 10 minute break (for us, coffee, a sigaret, and some stress ) I tested the videomodule in another BMW (3 E46 with navi) and that was working all right. Does anybody knows what this could be? |

I would bet 95% that your I-Bus signal is not connected. Another guy just finished an E39 retrofit, and he had the exact same problem. In his case, it turned out to be a poor connection on the I-Bus pin to the nav computer. Here is his success post. If you search that forum, you will find his other posts describing the symptoms and what he did to debug it.

Maybe your right. But how can I recognize where the I-bus signal is fitted on.
The retrofitcable of kufatech doesn't have (?) a connection like 12 pins (this is what the forum bimmerboard says). All connections are full, except the one in the front (where the original plug is for a radio, and on that plug i can fit my complete cable.) This is an image of the cable i have, maybe it says you something |

The I-Bus signal is part of the radio plug. It is on pin 9 of the round pin radio plug and pin 7 of the flat pin radio plug. The wire should be white with a gray tracer stripe and yellow bands around it.
Here is another test... does your radio work? If you can turn the radio on an off from the screen and change stations and volume from the steering wheel controls, then you have I-Bus in the new cable. If the radio is non-responsive, then start investigating the I-Bus wire. Out of curiousity, where did you get the retrofit cable, and how much was it? That looks like a fantastic solution for folks doing a retrofit without having to convert a full cable.

The radio is working indeed. So there must be I-Bus connection.
The cable comes from Kufatech (Germany) Their website is www.kufatech.de. The complete cable was € 265,- (TV-module cable included, and you can choose which radiomodul you have, BM24 of BM54) I know it's al lot of money, but it saves you a lot of work, normally...... Do you know what the signal has to be on the I-bus connection to start the system? I tell you why. We want to let the system work, without it is fitted in a car. I have the feeling that it is possible, but how........ Last edited by arjan_m; 10-20-2006 at 05:36 AM. |
