Finally! Glad to see someone tackle this install. I will be a similar build but much more simpler setup (no rear video) but I will be adding a rear USB port and 12v port and possible this http://www.sonicelectronix.com/item_...ANMRTR-04.html or something similar. So my son would be able to connect whatever tablet I will be getting him.
As far as apps for the galaxy for this setup there is a lot to choose from. I'm going to use this app https://market.android.com/details?i...l.torque&hl=en and this http://www.amazon.com/gp/product/B00...n=&s=&v=glance. Should be a cool effect.
There are also a lot EQ and volume apps to help tweak the sound. So far I'm leaning towards this app http://powerampapp.com/
I also ordered extra dash pieces just in case, cuz I know I will have to modify the opening and relocate the econ controls. What finish are you going with once you have your faceplate modified? I've been kicking around messing around with this http://www.youtube.com/watch?v=EmcdG...eature=related . And actually I've been thinking about opening my own small business doing this.... but anyway I will be posting my build once I start getting some components...
