Could you come back with reports about how's that working out ? Is it reliable? Does it need any monkey buttons pressing once you get in the car? The reason I'm avoiding a wireless NAS is that I fear it would complicate everything too much. I just want to be as close to what it is with stock stereo, like getting in, ignition on and drive... Everything should just power on and resume on itself.

Howdy dear gentleman,

I'm sorry to post in this thread, but I could really use some help from you Timur and the others, in order to do the same in my cheap Rockchip 3006 tablet.

Please, it'll only take a min or so of your time. Thanks!

Any love for an HTC owner? I have a One x and have been trying to accomplish otg + charging ever since I got my phone stock rooted with 4.1.1. Could someone please point me in the right direction to enable this? (I fell like putting my head through a wall)

You can safely use 5.25 volts with USB (at the connectors), One thing that must be taken into account is the resistance of the wires and connectors. My PSU output at its terminals is 5.3-5.5 volts depending on the amount of current being sourced. Its setup so that the higher the current draw the higher the voltage goes. This compensates for the resistance and maintains about 5.23 volts at the nexus charge port and 5.1 at the usb hub output connectors. If anyone wants to design their own psu and wants help building let me know.

Excuse me. Will this work on my future Nexus 7? N7>otg> 1tb hard drive and External dac while charging the N7? Will use my N7 for audio only. :D
This is my Dac = http://www.ifi-audio.com/en/iDAC.html
This dac has its own power supply.
