The forum's general opinion of the Concert system is pretty well-known (i.e. it's [censored]). I'm wondering if anyone out there knows much about the newer version fitted to the B6 chassis A4. Is it a better quality system? Is it possible to slot it into a B5 model, and operate the boot-mounted changer, without too much modification? I'd be interested to know, as I do want to dispose of my existing Concert system, but don't fancy paying for a wholsale system upgrade. Also, I'd like to keep the Audi "family look", if possible Can anyone out there help?
