Ok i have several questions about this mod before I start buying things. Hopefully you guys can help me out.

Platform:
2007 TL-S

Mod:
DVD through Nav system

Ok i understand how to install the Dom's unit for video but 1. How is the audio handled.
2. Do i need a source selector switch
3. Will it be expandable for future monitor installations


The DIY's i has read so far just walks through the install of the Nav2Go unit and I just wanted to clear up some questions. I am very handy with tools and electronics but like to be knowledgeable before i dive into something new.

 

from what i know:

1. for audio, you need a separate device like an isimple, pie x3, dice unit, or similar to add an auxiliary input into your stereo.

2. the unit should come with a switch to essentially turn on the nav2go box and switch from nav to video. the video 2 is normally supposed to be used for a backup camera, so that wire is wired to your reverse wire to reverse light. some people have been able to manually wire that to a switch and manually change to it. you don't have to use a backup camera for video2 because it accepts the same input as video 1.

and i don't know about #3.

 

Is it possible to use the factory AUX in the armrest or do I NEED to get an external unit.

 

sorry, overlooked the fact that you had an 07...yeah you should be able to use the aux jack for audio.
