C4 grand picasso Navi system

[Oppoe]

Hi and please forgive me if mi english is bad and if I posted in wrong place, I have a Citroen C4 Grand Picasso and I want to swap monochrome display to multimedia Navi display, I have all the components but something is wrong and I don't know what, the display is from a C4 grand picasso and the radio/Navi unit is from Citroen C5 rneg unit, also the lvds cable is from C5. The resolution is very bad I can't see anything on display.

There could be a number of issues.

The display screens are specific to the telematic units. RNEG (MyWay) uses a low resolution display. If you have a different screen (Hi resolution then it won't be compatible.
Next you may have the incorrect configuration in the BSI, depending on what system you had in the C4 Picasso before. There are a lot of configuration changes that may need to be made to upgrade from a non telematics system to a telematics system.

Mi previous setup was rd4 with monochrome display.
Is there any chance to be a problem with lvds cable, to be other configuration for C4 grand picasso.

The wiring harnesses are all different and additionally, you won't even have the correct aerials installed. It is much easier to go from having a telematics unit installed and then a further upgrade, but from RD4 it is a lot of work as you won't have the proper wiring, aerials nor the microphone (as this is integrated into the wiring harness for the telematics units and not there for RD4 / RD45).

Ok, so is not impossible just very difficult
Do you have a y idea if I can find somewhere the grand picasso multimedia screen pinout, maybe is different from the one from Citroen C5 .
