Land Rover Repair: 1999 Range Rover, ac system, letters and numbers

Question
In my stereo system show  EP E-02 and don't work, what i can do to make a work?

An another question. My AC system just work when the switch on with the key, but, when i started the vehicle AC  stop working and the letters and numbers on the screen disappear

Answer
The code means you exchange the radio with a service depot or a LR parts department.  At least, that's what we do in the USA.

Those disgnostic codes all lead to the same solution - swap the unit.

I can't say what's up with the AC without seeing it.  It sounds like the power goes away when the vehicle is started but I don't know what that would happen.  It's strange
