I have one installed although it was not fun to install. The plugs on the rear is different from the Defender and there is not much room behind that dash. They cost about $300 from china and come with Oz maps on a 4G microSD card. It also has a second Micro SD slot for media. The GPS is quite good but can lock up if you start pressing too many buttons. I have tried uploading a pic so will see what happens.
