You will need to 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 of the type shown here) are required to remove the radio. Many of the Becker units have horizontal slots along the lower edge into which the keys are inserted until they 'click' - this releases the internal clamps, allowing the unit to be withdrawn. Don't be tempted to try removing the radio another way or force it as you may damage the surrounding dashboard trim. The keys make it easy - you can find them in motoring stores or online.

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.

Some Porsche units, particularly those with a large screen (Sat Nav), cannot be removed simply with keys and can be fairly complex to remove, requiring that trim panels be unscrewed first. Also, many of these units cannot be decoded online from the serial number (thus removing them to retrieve the serial number would be wasted effort) and so we tend to advise that you visit a car radio specialist or a Porsche dealership for these more sophisticated units.
