Sat nav for a 04

[nonguitarmaster]

Hi, My dad just brought an 04 superb literally today. It has a tape deck and cd auto changer but he wants to change it to a in built sat nav system that plays cds and from his iPhone etc.

Does anyone know what systems are compatible so he can still use all his steering wheels controls and bonus if can link to the aready installed cd auto changer.

Sorry if this is been asked before and got any responses.
