It think it just comes down to whether you want a neat original factory look / want to, or, are willing to, change the original radio / want something stuck on your windscreen obscuring the view and leaving sucker marks on the windscreen and trailing wires across the dash. I don`t find anything wrong with the OEM unit. I put in where I want to go and it takes me there, what more do you really need ? That is a lot to pay though for the convenience and look of original factory.
