Hi

I have a problem with my PIONEER radio-dvd player AVH-P4000DVD.
I live in Greece which means the region number for my country is 2 and the radio FM tuner range is 79.50MHZ to 108.00MHZ step 0,1MHZ (EUROPE).
My unit which bought from e-bay is region number 1 and radio FM tuner step 0,2MHZ (USA).
Is anybody to help me to change the region number from 1 to 2 and also change the FM tuner step from 0,2MHZ to 0,1MHZ?

THANKS
