Head unit upgrade to seat nav unit

Leon mk3 head unit upgrade
Hi guys, a bit of advice please, have a 2014 Leon without the tech pack which means I don't have nav, or dab. I have seen an upgraded seat head unit which has nav and DAB, do I just fit it and it will work or does it require more for it to function as it should.
Thanks guys.

Basically you need to do lots of codding for your car as all second hand unit have component protection this coding can be done only in authorized SEAT service. And I am not sure if they will be keen to do it. If you don't have DAB now, aerial need to be run on your car also. Or you can give shout http://vagtec.co.uk/eshop/contact they should help with it
