So would it be a big problem to change the old built in sat nav in my 2007 aventura to one from a 2012 model.I guess the whole dash would have to be changed or could you just pop out the old screen and centre console and fit the newer one in just a thought i had because i like the style of the new one and it doesnt have that silly middle button that my kids love so much to snap off :lol: Cheers Matt
