I'm just praying the 07 centre panel is the same to fix as the old one, it only looks like a face lift so should be.
I was also worried about the lack of security face off, but it does screw in quite nicely and i'm thinking of making a facing plate to cover it over. i also have alarm with shock and glass break sensors fitted so hopefully i will be able to enjoy my unit for quite some time, (if i cxan get it fitted

)
I went with the avic as it is shown as a ford upgrade plus i got a good deal inc bluetooth and reversing camera, i didnt like the idea of paying for yearly updates which i heard you have for the kenwood sat nav.
