Discover media retrofit

hi guys,

i have just retrofitted a discover media unit out of a seat alhambra into my 2012 caddy.
i am wondering what i need to do to get the park pilot working ? it works intermittently and i have been lead to believe i need a new pdc module.
for some reason i have lost the pic of the caddy that it used to bring up also if anyone can help me get that back? is it just a coding thing ?

Gid

You need 1k8 pdc module and coding in media caddy picture

do you know what the coding is ? and is 1k8 module direct fit ?

I think first byte and you choose diferent car and pdc module you need adapter
