Petrol Dave, I'd be interested in the details of your AMI / MKII RNS-E installation and how much you spent on it. Is that the Audi AMI you are referring to?
I have a 2003 Allroad which had the dash replaced 2008 (at vast expense, by the previous owner) to allow installation of a (2008) RNS-E. A couple of years ago I looked at Dension Gateway products as a means of interfacing an iPod / USB drive with the RNS-E but it appeared that I'd never get proper track listings on the 2008 RNS-E. Firmware upgrade to 2010 was suggested but I never heard definitively that it would work and I gave up on that tone too.
Presumably you've been round the same loop, hence my interest. Were you able to sell on your old MK1 RNS-E?
Any thoughts appreciated,
Peter.
