octavia sound system up grade help

[Badger Driver]

first of all had a friend in the car who decided to turn the music up full and he damaged a speaker in the passangers door and tweeter in drivers rear door, so i have decided to upgrade all and use an amp.

i have all the wires in and all the speakers in the dash just need to get them connected to the headunit to run an ampifer,

no for the question is there a lead you can connect into the back of my navigation unit to allow me to run rca leads, i know there is one for the golfs and audis but ths doesnt fit my head unit

i mean all the wires hid behind panels and the speakers in the door, so car is totally standard looking
