i just installed an Avic-D3 this weekend and on the first power up i got "insert the appropriate disc message. I put in both the east and west disc it says that it is checking them and then it says to eject and insert the correct disc. i have asked the installers where i bought the unit and i also called pioneer and they said to ship it to the repair center.
Does anyone know what causes this and can it be fixed without having to ship a brand new unit off to be repaired?????
