If you have a facelift it will take one, pre facelift you have no chance, indeed without serious dash rejigging. Best solution is to go for a pop up screen style single unit.
Use to have a single din pop out screen it was amazing until my wife found a way to break it. Will be getting another once the freelander stops breaking which is clearly going to be never lol
I keep looking at those type of head units. Just not sure- usually you would pay £££ for all those features on something half decent. The age old problem of my cheap buy twice...
