I think the OP is referring to the MK4 satnav unit

Hi what im referring to is there a box near the battery that is linked to screen in the dash.or is there a common fault to point me in the right direction,like a broken wire or wiring fault,just some ideas would be appreciated thanks

The box near to the battery is the BM54 radio module, they are a known failure. There will be a lot of info on the internet, not sure if they cause a blank screen.
