3-series (E90/E91/E92/E93) [2006 - 2011]

Replacing the well regarded E46 3-Series, the E90 debuted in 2005 with quite a conservative design compared to other contemporary BMWs. It came in Sedan, Touring, Coupe and folding hard top Convertible body styles.

The sound system was an early version of that now found it most BMWs with 100mm mid-range speakers in the doors and under-seat subwoofers providing the bass. Models with the Logic 7 or Harman Kardon sound system have a fibre optic amplifier that make it difficult to change the original radio.
