[quote=KiwiJochen]You have no ibus data connection from the nav / audio system to the rest of the car.

Hello Jochen

I used a cable from a car which had both DSP and Navigation, so 'm not sure if I got the IBUS (which colorcode does it have in a E39 1996 ?)

I assume that the IBUS worked since I can control the DSP amplifier and I can change the laguange displayed in the instrumentcluster from the board monitor

A friend of mine, told that theres supposed to be a connection between the instrumentcluster and the bardmonitor - but he coundn't remember exactly

I haven't recoded the car yet

Best Regards
Xenon-Jensen
