2012 C4 Picasso - Change Stereo Headunit to add Bluetooth

[GiveMeABreak]

This is just from what I have looked up and the harnesses are very equipment and build date specific. It's another reason why Citroen do not sell the factory-fitted Nomad hands free kit as an official accessory, but only provide approved aftermarket systems, because they have to be fitted at factory with the requisite harness and other conenctions.

While you're stuck with the FM, try either 87.5 or 107.9, those are bound to be the frequencies with the least interferences.
Possibly unscrewing = removing the antenna will also make it that regular stations are more difficult to pick up, whereas the transmitter is close enough for that not to matter.

The wiring may be present for a retrofit (it was on our 308), but Marc is correct on the need to reprogram and the need to fit a microphone.

Hi,

I have a 2006 C4 with the most basic stereo, no Bluetooth/hands-free, and a one-tone dash screen.

I would like to retrofit a satnav version, exchanging: main unit, the dash screen and the steering buttons, as they're becoming inexpensive second hand.

I have the following questions:

Is it possible to install all items directly to the existing connectors?
Is there any part I'm missing?
Would it need coding?
Any tips, ideas?

Hope these questions are appropriate to this thread.

Cheers.
