I have mk4 nav and dsp so every thing is located in the trunk.
Getting ready to install my avin 4 and looking at Reslser's install wiki page it does not recommend installing it behind the dash where the connectors are for the screen.
It recommends tapping right by the Quadralock farka harness. Which then would require me to get a USB extension cable BUT it doesn't recommend using any extensiona either.
Says something about certain functions will not be able to communicate.

This is a catch 22 lol
Anyone who had mk4 nav, where did you tap in your iBUS and how well is it working?
