I got the local fitter to give me 'movies in motion', basically it is earthing the handbrake cable. This makes the TV, DVD and phone work on the mov. I found not being able to dial out unless on preset numbers a pain. I'm no fan of multi screens around the car either so the passengers can keep an eye on the screen while I drive - as yet I haven't actually used it apart from in London rush hour traffic to listen to the news.....so really one of those things you want, then you get, then find you don't use!
marky, thanks so much for summarising all of this, really helpful. The only problems I have had are updates (which I now have good instructions for so will try next week), and the radio reception is hit or miss, not decided on what to do about that yet. Also re map updates, I'm not clear on whether they have to be done in the back SD slot or front, conflicting instructions from Kenwood or Garmin.
Other than that it is a great unit, and so much cheaper that the VW ones. Regrets, I can't get the optical parking sensor, sometimes the unit is slow. Also the standard splash screen from VW is hideous and totally lacks effort. I tried changing it in the past but no joy so will again follow these instructions. Reception is sometimes iffy and seems to get interupted by mini-cab radios (!). Last one is the unit lights cannot be wired to come on if the unit isn't on, but there is a little triangle near the 'on' button to assist, would be good to know if this was addressed in the latest unit.
Good points, it works with the MFSW and actually does more than the VW unit. Also looks very OEM, especially if you also change your aircon knobs for the round/silver type.
oh and it isn't compatible whatever you do with iphones and sms, i called and asked. one nice touch as well is if you hold the FNC key you can switch off the screen alone, handy at night as it can be quite bright.
overall i like it, and certainly was a better purchase than some of the dodgey looking ebay units, plus I know it isn't nicked!
