fitting difference SATNAV to S6

[pdpaxm]

Hi,

I have a 2001 (51) S6 AVANT and it has the SATNAV fitted in the intrument panel, still very good though.

However I do miss my map etc..

I was wondering if it is possible to fit the SATNAV with TV/DVD screen in the dash to replace the symphony II stereo and how hard is this to do?

Cheers

Andy
