Hi everyone;

I'm looking for anyone that owns a MCS R56 early years (2007, 08, 09 and maybe 2010) with the old navigation system; that have done a radio swap. I want how many features you loose or how's the functionality. I know you loose the Nav so the screen on top will be use less (or will it still work??). I want to do the swap but will like to understand what am I getting into....

Or if anyone knows the functionality of the wire harness for the screen?...I know that the one connected to the speedo must bet the one for the gas, check engine, etc. There's one with 4 cables and one that is a bundle.
