It sounds thin, overly bright and harsh, and sorely lacks a low end. This mod involves DIY installation of a compact plug-and-play multichannel DSP amplifier.

The Navigation-20 system was a dealer fit option and was never covered by the three year free map updates. The latest and last update is the 2011/2012 one. This is done via USB and each USB stck can only be used once! The product was only for the W204/w207/w212 NTG4 audio-20 cars. So cannot be fitted to model year 2012 or newer cars.

For NTG 5.X in 2015 made CLA (pre-2015 CLA is NTG4.5), if it comes with the Comand option, u can upgrade it to be Apple Carplay compatible.
