It really is a minefield mate

I've had mine for years and the wifi broke and I keep going through usb cables lol, but the old girl kicks over. Be obsolete soon though unless they invent something worthwhile doing on euro 5/6 etc.
Hence me suggesting that you Swerve it. Your van will get the latest update post 2011 but I really don't think they're bothered making more on an out dated van.
Incidentally what year is yours?
