Our service is personal, not automated, so if you are not sure which numbers to give, provide us with all you see on the outside of the casing and we will check them for you.

We aim to respond by email usually within an hour, a little longer at weekends. These codes are at our standard price of £7.95.

After submitting the form, you will be forwarded to our payments page. Note that your request will not be actioned until payment is received. Our service is inexpensive but not free. We aim to give a good service to paying customers, with the assurance of our money-back guarantee: If we are not able to supply the factory-set code for your unit, we will explain why and suggest how best to proceed, and we promise to refund you (less 95p to cover the payment processing fee).

Our Rover/MG codes service is focused solely on vintage Philips and Grundig radios, ideal if you are restoring a classic car. Unfortunately we are unable to supply codes for Clarion radios (model numbers prefixed PU), Alpine radios (serials prefixed AL); later Philips units (fitted after 2000); and later Grundig radios. The available Rover/MG database stops in year 2000. If your serial number is more recent, we will pass on whatever information we can and refund you, less 95p to cover our non-refundable payment charge.

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.

This independent website provides useful guidance on how to remove car radios and sat-nav units from vehicles.
