I did that, it worked for the first time!
thank you so much.
I have been trying to contact Pioneer for half a year now about that issue and it took exactly 5mins. to fix it with the self-calibration.
I read Pioneer will charge $200 for that plus all the hassle with removing of the unit from the dash etc.
They should give this routine in the user manual.
Anyways, thanks a lot for this wonderful help, it is great!
Just to reapeat what was already written in the link kindly given to me:
cheers
