Hi - happy with what I received but not quite what I wanted - my fault I assumed that service manual would also include operational instructions which is what I needed - all I needed to know was how to turn the radio - thanks
This service manual helped me to repair my PIONEER. Iam very satisfied, that I found it here.
Even the price of manual was not so high that person would not be able to spend a few money.
But that is very worth spent money. Thanks
