91 10 Pcm: Remedy

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

Input the PCM code. If the code card is unavailable, the PCM code can also be read from the DME control module (under "Vehicle data"). This code is also available from the Porsche IPAS.
Switch on the PCM with a free panoramic view for approx. 20 minutes (to load GPS almanac).
The date and time are also adopted once the GPS almanac has been loaded (see step 4 ); it may be necessary to change over to summer time (daylight-saving time). This time is transferred to the instrument cluster. If the time is then manually changed by means of the instrument cluster, this time is adopted by the PCM and synchronized with GPS time.
The stored stations are displayed again when station buttons 1 to 6 are pressed.
The telephone is enabled again when the telephone PIN code is entered with the SIM telephone card inserted.
