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 offer advice, and we promise to refund you (less 95p to cover our non-refundable payment charges).

If you have any doubts about your ability to remove the radio from the dashboard cleanly, without scuffing the surrounding trim or worse, we strongly advise you to visit a specialist radio installer or contact one of the many good mobile specialists. This advice is true for any vehicle, but damage to higher value cars can be prohibitively expensive to put right.

Pull the radio from the dashboard to read the numbers from its chassis - this will be on a printed label or engraved on the metal case. Extraction 'keys' (often the type shown here) are required to remove the radio. Becker units fitted to Ferrari have horizontal slots along the lower edge into which the keys are inserted until they 'click', releasing the internal clamps and allowing the unit to be withdrawn. Don't be tempted to remove the radio any other 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.

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