Well my sat nav has packed up again (laser!!) so rather than spend more on it I have bitten the bullet and purchased an new unit. The new unit came with an adapted fascia for an a8 i think! This is of course is no use to me as you all know my car is an RS 6. So a quick text to someone and he sent me a link which I must say I found very helpful as I was quite apprehensive about attempting this!!

Here it is

All in all it took me about 20 mins to replace both fascias and if I can manage this then anyone can

I must say Thank you to Ian (IT) for both the quick delivery of the unit and the help with the link
New unit before swopping fascia.
My faulty unit with the fascia I need to swop over.
