CID Firmware Update
If you have a Colour Info Display in your Astra or Zafira which only shows 2 lines of information on the Board Computer, it can be updated to the 3 line version.
Once updated it will allow you to have the VXR and OPC logos at startup.
Some users have noted that following update, the Range warnings on the display for low fuel do not show up, you still get the warnings on the fuel gauge. If the display warnings for Range are important to you, then do not update the firmware.
