upgrading to dsp in '04 3.0 X5 with NAV.

[gabyX5]

hi guys,
does anybody have any pictures of the wiring of DSP wires from the amp to the sub? I wanna up grade to DSP. I have the amp with the 3 plugs cut and the factory sub.
Any help please?

The pictures are all in the WDS, which has full wiring details of everything - all cars, all options.

Get a copy, then you will understand your car.

I wouldn't really call this an "upgrade", better results can be had via aftermarket and at a lesser cost.

Did you ever find out about the wiring ? I too am looking @ similar installation, thanks for any updates,

Take KiwiJochen's advice and get a copy of WDS. Print a copy of non-DSP wiring and then one of DSP wiring to see which wires to swap.
I helped a friend retrofit DSP in his 2003 E39.
Depending on where you get the amp from, it should be coded for your vehicle type (the equalization is different from model to model) and for Nav or non-nav (you will get sound for about 10 seconds, then mute if this is not coded correctly).
You will need to tap into the I-Bus so the car "sees" the amp and the radio module (BM53 or CD53) will output the correct signal level.
