Sorry if its been covered a thousand times, I have an audi concert single din, I'm aware I'd have to get a new centre console because of the CC, would I lose the cup holder near the vents? Is there anything else I need to buy as well as the actual rns e unit? My car is a 5( plate sportback without a MFSW, but has DIS, I'm just after iPod connectivity and phone call usage etc and like the look of this bit of kit.
