As new RS6 owner, and loving it I am now thinking of changing the factory fitted Sat nav for a touchscreen Bluetooth DAB sat nav entertainment system, you know the sort!

There's a lot of 6" screens out there, and have seen an Alpine 8" screen but crazy price, so may just opt for a 7"

I have come across icartech in berlin, anyone know if they are any good? ICARTECH S730 for Audi A6 4B (C5)

Trouble is I am in the UK, so fitting it may be a challenge. Any thoughts, advice welcome as am quite new to this
