I have the factory Alpine Navigation System from Scion and I'm trying to bypass it so I can watch DVDs whilst driving and access all the menus when driving as well.

I read about buying a PAC TR-7 to bypass Alpines and that is what I did. I have it and I've read the instructions and they confuse me on where to splice and connect wires.

Does anybody have any experience with install a PAC TR-7 in their Scion Nav System?

 

If you search, you will find how to bypass it. There should be a couple of DIY on how to do that on here... I believe it is a wire going to the E-Brake, but 100% sure.

 

Well no, I'm asking more specifically how to bypass it using a PAC TR-7.

I've googled for hours to come across the same thing. The instructions for the TR-7 states to do this:

Connect the GREEN wire to the Alpine’s remote wire (Blue/white wire)
Connect the BLUE wire to the Alpine’s foot brake input wire
Connect the WHITE wire to the Alpine’s parking brake input wire.
Connect the RED wire to vehicle's accessory 12v.
Connect the BLACK wire to ground.
In this configuration, relays are not needed. Do not connect any other
sources to the WHITE or BLUE wires of the TR-7.

My question is which one is the Alpine remote wire? I can't find a wire that is blue/white.
Which one is the foot brake input wire?
I know where the parking brake input is.
Which accessory 12v should I plug in the TR-7's RED wire?
Where should I ground?
