CAR RADIO DECODING
service is for units not covered by our serial number decoding service.
Manual decodes have
to be sent to our workshop for decoding,
we read the code
from a memory IC (EEprom) inside the car radio, the lock counter is also reset if required, the radio will then be reassembled, checked and sent back
with the correct code printed on the invoice.
EEprom - Electrically Erasable Programmable Read-Only Memory
some of the tools and methods we use for decoding
and programming car radios, some radios
can be decoded by connecting a probe to
the EEprom, others need the EEprom
We have programmers for all types of EEproms and micro processors, with regular software updates we can decode the latest models.

the micro processor has to be removed as
the EEprom that stores the code is
inside it. This decode takes around an hour.|
is part of an EEprom dump from a Philips Car CD player, the radio code
is stored on the bottom line (9882), the EEprom also stores other data,
such as, the radio serial number and radio station presets.
All manual decodes are done and
re-sent the same day they
Decodes can be done
while-u-wait at our shop.
Note: some models can
take up to 1hr.
