im installing an f500bt and the pioneer amp designer for it.

on the amp they have a spot for a harness to radio and to navi. where do i get the harness for the "to navi". which box should it have been in? im pretty sure i never received it.

hmm nobody else has come across this??

does anyone know where i can get one of these without having to deal with calling pioneer.

It looks like this. Its in the ND-G500 amp box, I also didn't notice it in the beginning. If its missing then contact whoever you bought it from.
