Hi there Just got my first 'S' Audi and am just blown away, it ticks so many boxes. Wondered if anyone else has gone down the retrofitting route? I've got a fairly basic spec S4 Avant (Late 2009). Luckily it's got the standard interior light pack (keep discovering little lights that i didn't know exists like inside the door handles!), and auto lights, wipers, etc. and also the MMI 3G High / HDD nav. I was thinking of upgrading to B&O but it's about Â£1895+VAT - seems v pricey but then the sound is much better. My Allroad had it and I really noticed the difference. Do you think the Digital TV is any good? Anyone got this?? What about Keyless entry / MMI 3G Plus, is that like Audi's CONNECT system??
