retro fitting rns 315

Hi iv swapped my stock factory cd player for a rns 315,its fitted & working but my climate & rear parking sensors are not showing up on the display, is it easy to recode them with a genuine ross tech cable any help would be appreciated or if anyone local to birmingham want to earns some beer money pls get in touch cheers graham

p.s iv had a new later canbus fitted by local skoda dealer to avoid the battery drain issue.
