Radio Unlock on a A8 Delta CC

[Mark R]

Must be a pre-2000 A8 since it has a delta radio.  Either way, to pull
the head unit (radio) you just need the radio removal tools.  I doubt
anybody other than a dealer or stereo shop would have them available
for an Audi.  You might make due with some SMALL thin screwdrivers,
but best to not mar the unit.  I have the tools, but unless you want
to come to Binghamton, NY that does you no good!  =)

My family had both a 1999 and a 2000 A8.  Anyhow, good luck.
Despite what Brett correctly says, if you don't have a relationship
with them, expect to pay the dealer their min charge (usually $35. or
so) for the service.
