Can Bus / K-Bus confusion

What's the difference?

I'm trying to install a Parrot Bluetooth Phone set up into my 04 X3. The installation instruction are clear but I need to identify CAN LO, CAN HI and K-BUS.

Parrot's diagram does not correlate to my vehicle wiring.

Where they say show the 2 CAN pins they are completely missing from my car's head unit plug.

And they don't say what the K-BUs wire is.

CD Port of my head unit shows 3 wires:




The main loom shows no wires at all where Parrot reference the CAN wires:



I know the red white stripe with yellow dash is a BUS wire...


Any help isolating the above wiring colours much appreciated...!

E46 doesn't have a CAN bus, as far as I know. If the parrot is designed to integrate with an e46, then the CAN +/- shouldn't be necessary. Try leaving them disconnected and see if it works, my guess is the integration kit is designed for several different cars.

Oops, looks like your fitting for an X3. I'd still leave the CAN bus out.

Thanks.

I have since found out the E46 / E83 does not use CAN. The Parrot works without it but the steering wheel interface (called a MultiCAN) requires CAN and or K-Bus.
