hi ,

just received the new C4, as a music fan I tried to find out where can I install my aftermarket unit ,so there is no space since the AC and the radio sit on the same plastic plate .

so the only solution is to use some kind of sophisticated in line. I found this one MS-8 by JBl
which takes the high voltage signal and allows you to go into an amp

the only issue is that I need to find out about the pin out of the RD5 .(I think its a standard connector I just need to which standard)

please help

The RD4 pinouts are here: - Click Here -

The RD5 quadlock connector at first glance looks identical to the RD4.
The white block at the bottom will be the link to the USB/jack port which is next to the cigarette lighter.

I'm planning to install a aftermarket radio as well. I planned to put it rigth under the radio display. But on your picture it seems that there is no space for my planning.

Did you check the radio connection as well. Any chance to install a steering wheel intervace adapter.

Thanks for your replay in advance.

I expect installing an after market radio isn't too different from the old RD4, however the steering wheel controls are different and I've yet to see the modified fascia panel (which is very big) for the nouvelle C4 though there may be some available in France.

This is the best I can offer, as I've not taken my radio out, assuming you have a VTR+ or similar.

I know this picture.
I have also access to the Citroen servicebox.

The problem is not the Radio. I can't get out the
ventilation shaft above the radio. If the ventilation shaft
is not removed, you can't remove the multifunctional display above
the radio.

I've now done.
First you need put the glasses fold with multi-function display out.
On the way the upper ventilation shaft will get out.
The rest is self explanatory ...

Hi there, I am trying to fit a no holes bracket for my iPhone to my DS4 and as such need to get the centre console out as I see the op has done here.

The bit I am struggling with is, I am pretty sure I need to get the air vent at the top (I have the emyway?, I think) of the multimedia using out first, but I have no idea how.

Is there any diagrams I can use as a guide, or does anyone have any experience with this that could help?

Much appreciated.

Brodit clips are the best. They are designed to clip over the vent surround wit no other fasteners.

Not the cheapest, but by far the best
