Hello all, I'm brand new to this forum business and I have my first query. I am just about to purchase a RNS E head unit from an A4,
but before I do, I want to ensure it will be compatible with my B6 05 A4 quattro cabriolet. Will all the functions work, DVD, nav, iPod
etc. How easy will it be to install? Etc, etc.
Also, what's the difference between RNS D and RNS E?
