Hi, I’ve recently upgraded to a Range Rover 2012 V8 Tdi Vogue with front TV and DVD. It seems the sat nav runs off a hard drive and supposedly has to be updated by the dealer. They’ve quoted me a staggering £540!! Seriously unimpressed. Anyone got any ideas how to overcome this please...

Oh great news. Thanks

im planning on replacing my Rocker cover gaskets but I've recently been led to believe that you have to degas the air on in order to remove an air on pipe before removing the Rocker covers. Can anyone confirm either way for me please. Thanks
