Audio Systems/Alpine CDA 9805


I have a AM\FM car radio\CD player that does not work.may you be having a service manual ? i have downloaded a CDA 9805-R service manual but it is not the same as my unit.

Sorry, I do not have the manual nor was I able to find it online.

Are you certain the 'R' model is not the same or very similar. It would be surprising if not so. Sometimes an alpha model is the same model for a different country but the same chassis.

Best wishes.
