Important Notice:
The radio must be added to the car through diagnostics. Without proper BSI mapping, limited functionality, error messages or the radio not playing at all can occur.
Assembly advice and recommendations:
– Always disconnect the minus terminal of the battery and wait a few minutes before disassembling the old car radio for safety and protection of the electronics.
– Use the correct extraction keys for the car radio so as not to damage the mount or faceplate.
– Check the condition of the ISO/Quadlock connectors – there must be no broken pins, pulled contacts or signs of overheating.
– During installation, ensure that the radio is firmly seated in the shaft, so that there are no hums and vibrations while driving.
– After the mechanical assembly, connect the battery and perform the transfer (pairing) of the radio with the vehicle using diagnostics (eg DiagBox, Lexia, PP2000 or compatible diagnostics for PSA).
– After completing the diagnostic assignment, test:
– turning the radio on and off
– switching stations and sources (FM/CD)
– control under the steering wheel (if it is in the car)
– communication with the display (showing the station, volume, etc.)
– Be careful of voltage surges – during diagnostics do not change the battery connections, do not disconnect the connectors of the radio or other control units.
– If you are transferring a radio from another PSA car, it is advisable to first “decode” (deregister) the radio in the original car and then register it in the new one – this will facilitate the proper functioning of all systems.
