Teaching Car Radio
NOTE:
- If a new car radio is to be installed in a vehicle, the PCM2/CDR23 code specified in IPAS must be used.
- You can get the codes from IPAS or from your importer by specifying the vehicle identification number.
- If possible, before the car radio is removed and replaced, a read-out of the vehicle data should be obtained using the Porsche System Tester.
- During coding, the power supply for the Porsche System Tester should be guaranteed. Connect a battery charging unit to the vehicle battery.
- Symbol for the TAB key = ->|
- Instructions for the Porsche System Tester have a higher priority and are to be followed where descriptions deviate. Deviations may occur with later software versions (as of 15.0).
- The procedure given here has been structured in general terms; different texts or additions may be displayed in the Porsche System Tester.
