  1. Preparation – Charge car battery (12.6V+). Burn firmware to a quality CD-R (DVD-R preferred for larger firmwares). Some newer updates can use SD card, but DVD is safest.
  2. Update start – Insert disc → Press & hold Setup + Eject + Mic (for Audi) or Setup + Eject (for VW). Screen goes into SWL (Software Loader) mode.
