I've booked Hazzydays (http://www.vwcruise.com/) to come out next Thursday to fit some toys to my A3. I've sourced a FBMFSW and RNS-E myself, and they are going to fit these along with Audi Bluetooth, which they're supplying. Their total bill is quite upsetting at £1010 inc VAT, but for this they are supplying a pile of parts - the Bluetooth, the ECU and slipring for the steering wheel, and all parts to convert the dash from single din to double din (and trim down my climate unit), and fitting it all. It's a lot of cash, but a lot of work, so looking forward to having it all done. I've got to say they have been really helpful so far, with explaining the various upgrades, giving me the different options, and helping me decide what is required. If their fitting service is as good as their pre-sales service, then I really won't hesitate in recommending their services to anybody!
