Kevin, thank you very much for your advice and time, it is very much appreciated, I will certainly keep you in mind for any future work I might need. (Peter Darker - MG ZT)
You will need to pull the radio from the dashboard to read the numbers needed from its chassis - this will be on a printed label, engraved on the metal case, or both. On some Rover radios, extraction 'keys' (often of the twin fork type shown here) are required to remove the radio - don't be tempted to try removing the radio another way, or to force it, as you may damage the surrounding dash trim. The keys make it easy - find them in motoring stores or online.
Some Rover units are extracted using a suitably sized Allen key to release bolts on either side of the trimplate (the small holes are visible without removing the trimplate), then pull the radio free. Others (including the MG ZT) require the trimplate surround to be unclipped to reveal two larger screws top and bottom - undo them and then pull the radio out.
We no longer offer codes for Rover
