Hi there,   Does anyone know how to access/remove the navigation computer that controls the TFT sceen on a C5 Exclusive.    I know where the VDO dayton Map CD player is (Right Hand Side storage bin below steering wheel). That's not what I'm looking for.   I need to try and save £1300 by finding and soldering a dry joint on the screen controller which is causing intermittent on/off faults with the centre screen (as diagnosed by Citroen).   Your help would be greatly appreciated. It will save me alot of time pulling the car apart.
