Traffic is the older unit, this is the newer version that has an app button instead
It will need unlocking to work in a vehicle outside the one it left the factory in but as mentioned above
@Dav-Tec is your man for this and can do it remotely with you (as long as you have an SD card) and think it costs around £80-100
If you want car play to work you may need to swap your existing usb socket in the van (if its not an apple compatible one) and thats about another £30 at a guess
