Skoda Superb mk2

Production years 2008 - 2015

The mk2 Skoda Superb has three original radio options, the basic Skoda Swing radio, the mid range Skoda Bolero radio and the high end Skoda Columbus navigation radio.

The original radio will determine what parts are required for fitting a new aftermarket stereo.
The Columbus navigation radio is shaped like a standard Volkswagen radio and is based on the Volkswagen RNS510 navigation radio, because of this a Volkswagen radio fitting kit is needed to fit a new stereo.
The Swing and Bolero radios are bigger than the Columbus and take up more of the dashboard space, because of this an additional adapter panel is required to convert the dashboard to match a car that has the Columbus radio, this then allows the fitting of a new stereo.
