Single DIN unit install: How far back

[toyotas4all]

Does anyone know how far back single DINs can be installed? Would I be able to fit it with the original factory bracket?

The reason I ask is I'm trying to create a car stereo solution using a 7 inch Galaxy Tab. I'll be running the RCA audio cables from the Galaxy Tab's 30 pin connector into the back of the stereo (assuming it has RCA audio inputs). I'll be creating a frame to hold the tablet in place that slides in and out of the Double Din slot in the console. I want the single DIN stereo as far back as possible so that after putting the tablet in, it won't stick from the dash.

Why not just run the Galaxy Tab into an amp and call it good? Well what happens if I forget the tablet one day? I'll be completely stereo less. With the single DIN in place, I'll atleast still be able to listen to the radio/music/etc etc.

I am aware that there are China made units that are already android based, but by doing this, I add security in the fact that my "double din head unit" is removable. Once I remove it, I can even make it look like my head unit was stolen by having random wires sticking out. =).

Great idea with the tab. I too think this is a better way to go. There are some similar mods on youtube. And I think Scorche sells a swival mount for Ipad
As for depth room, it'll depend on your new unit. There's some room there. It's quite easy to remove the OEM to have a look.
Mine was made especially for 10 gen Corolla and fits to all mounting as OEM.
