The dealers and some authorized service centres for your radio have the
factory device that can unlock your radio. They have to access the EPROM and
re-initialize the firmware.

There are some models of radios that have a master re-set code that can be
done from the front panel, but I think your unit may not.

Most dealers will charge 30 to 40 minutes of labour time to unlock a radio.
This can amount to an average of about $40 to $50 US.

I have a friend that his daughter screwed up the code a number of times. He
simply took the car to the dealer, and forked over the few bucks to get it
unlocked.
