Hello,

I want to retrofit a combox in a F21 with HU_CHAMP2. I already found which part number combox I will need. But what about the wiring harness. Is there a plug and play wiring harness available which I can buy? Or can I make the harness myself?

Any help is appreciated.

So just replace unit with entrynav, code it and that's it? I assume it is not plug and play, or am I wrong?

You need to connect the microphone and bluetooth antenna obviously

But you will need to reroute that to the new HU

if he has phone bt, but not combox, the mic is already in the hu.

just fit entrynav and code out nav function

Just to be more clear:
You dont need any emulator if nav is not used.
Your unit does not has the capability to reproduce music via bluetooth, entrynav has.
as SweetBMW mentioned, vo code without nav function and you are done.
