I have a engine code that flashes up on a diagnostics tool but not on the dash it’s probably to do with blue and me not working with the head unit but not to sure about that. But if you want a double din media station I really do recommend the xtrons unit as it’s shaped like the original unit and slides straight into the slot without having to buy any facias or adapter cables and it provides everything like Bluetooth gps DVD/Cd player it even has games on it. it works a treat for my needs it also has all the slots for a sub unlike the original unit
