At the moment I think it's a pioneer.
I was looking for something like this, something so I could play YouTube and my google maps through. YouTube so I could play for the little one and also Bluetooth. So I was delighted when he told me he found something for it. Ill be getting it in my yoke soon so Ill stick up something on it when I get it.
It costs roughly €500, €450 for the system and then you need something for it which is €50.
I'm also on the lookout for a unit I can display my oil pressure and other stuff rather than actual gauges.
