After going around and searching I ordered an OTG Y cable that I though was going to work but wound up only charging the tablet but wouldn't allow it to go into OTG. Really didn't feel like ordering another one and having it not charge or what ever. So I decided to hack and splice my own together. Also wanted to have it hooked to a USB hub for things like DAC, SP 3 controller, various drives whether it be flash or hard drive , as well as possible web cams in the future.
SYBA SD-CM-UAUD USB Stereo Audio Adapter
BELKIN F5U404PBLK USB 2.0 4-Port Mobile Hub
Nexus 7 NVIDIA Tegra 3 1GB Memory 32GB
For now I'm using a hacked cigarette adapter for a step down to 5v for the USB hub
2 Large safety pins(you'll see)
cables were in a drawer....you all know the story
Onto the pictures
Dash panel with the heat vents removed. The center bar was removed and the entire hole was slightly enlarge a bit more to get rid of the accent bead the goes around the area.
Next I went online and found a cheap 8 gig unit with a broken screen to use as a mold and wrapped it up and made an place for the release.
Fun with fiberglass
After letting it cure and some clean up
Some shaping got it to fit the area I wanted to take up. The dash originally leaned toward the driver a bit. I didn't want it like that I wanted it to be straight so it would be easier to view for all passengers for watching movies yada yada.
Test fit with radio in place
