Ah okay, that's not too bad then. Personally, I think that the benefit of literally having a sat nav available at the flick of a button (rather than getting it out, mounting it to the windscreen, plugging it in and waiting for it to turn on) is worth the cost, and the only feature I miss is the ability to have POI notifications - I do love voice recognition with Audi Connect where I can say "online destination alton towers" for example. I find that very useful and it works for most places, as well as the ability to use the wheel as a touch pad...but each to their own! I always used to get frustrated with the cable but looks like you've got that covered.
Did you enjoy Alton Towers? Thorpe Park was pretty quiet ð
