No need to cut. Just plug in to the CD changer cable.

I use crocodile clips and connect to the visible loom connector above the CD changer on my E39

So does the USB version come with a connector to do this, or do you have to make your own up?

NBTBRV8 - Rolf's interface consists of a USB connector at one end and 4 pins sticking out vertically at the other end. The USB is connected to your PC with an appropriate lead, and the 3-pin i-Bus connector going into your CD player (the most convenient place to access the i-Bus on the X5) is unplugged from the player and plugged into the IBUS/+12V/GND pins on the interface.

Jochen uses an alternative option of DIY 'jumper' cables to tap into the i-Bus lead with croc clips, with the other ends connected to the interface pins. Alternatively, you can do as some others have done by breaking into the i-Bus lead and creating a permanent and readily accessible flylead.

I used a 12" floppy drive power cable extension, which has the correct connector to plug into the Dreseler interface and tapped into the 3 leads from the CD changer. That allowed me to leave the connector accessible without removing the trunk panels.

Don't leave the interface plugged into the connector when you're not using it. It'll hold the I-Bus down and your radio, cd changer, etc. won't function.

Interesting points NEG, thank you.

except the startup logo and warning screen goes after 8 sec there is nothing i noticed!!
mmm also the prespective map view.... but whats the value from that when the street names are not there anymore!!:dunno:
anyway, new look doesnt heart :confused:

In the 3D view street names are not visible- it's normal.... Should be like this

You mean perspective view? Then yes.
