The new 911 GT3 is equipped as standard with the new CDR-30 audio system with a 5-inch display (monochrome) and MP3-compatible CD player. An integrated six-disc CD autochanger is available as an option.

The FM dual tuner with RDS diversity, a total of 30 memory presets, dynamic autostore and speed-sensitive volume control are, as usual, part of the standard package. Just like the high-quality sound, which is delivered by four loudspeakers and an integrated amplifier with 2 x 25-Watt power.
