The radio may require a security code due to the battery being disconnected. A Landrover dealer or forum would have information regarding this.

I’m guessing radio security code too. The car manufacturers are trying to discourage radio theft, so they install a type of radio that if the power ever becomes disconnected — like a thief swipes it from the car – it will no longer work unless a security code specific to that radio is entered. This may or may not explain the other differences you’ve observed on the dashboard. Suggest to get the radio working again, then if the dashboard problem remain, post back. Given the Halfords reference, I presume you are posting from the UK, right?

That was my first thought as well.
