Rns510 and fiscon coding

I used to have the rcd300 and had a menu on the mfd, since installing the rns510 that's gone so I assume it needs coding also I've got the amp under the passenger seat so I assume that's needs coding to, then I've brought a fiscon basic plus and i know that needs coding, so the question is what bits on a vagcom do I need to change to aid the helpful person who ends up coding it for me! Is a mk5 56 by the way and have no idea on the canbus and its a 510 version b with new maps thanks
