I recently started to install a Nexus 7 to be used as a head unit in my car. I have it fitted and looking nice with the line output running to the aux input of my car stereo which is now mounted in the glove box. Now I just need to power it!!
So my questions are,
- can I split the 12v that currently feeds the ISO connector to the stereo and use an adapter to get the 5v 2a that I need? Or is this dangerous?
- It would make sense to use the "switched" 12v volts so the tablet is only powered when the ignition is on. Agree?
- If I can't use the twelve volts that is currently powering the car stereo at the same time, where can I get power from?
Thanks for your time
