I thought I'd better drop this thread in here as well as the B6 forum:

I've bought an RNS-E for my 2004 S4 (B6) but I want to make sure I'm getting the right cables.

I considered an eBay special but I'm worried it'll be a waste of money if it isn't compatible with my CD changer and Bose sub and amp.

On the other hand, Kufatec do an RNS-D to RNS-E upgrade kit, although £70 + shipping is way overpriced.

Doe anyone have a recommendation please?
