The things that stops me from directly placing my n7 into the dash are these.
1. tethering (iphone:n7) certain apps don't recognize the Bluetooth tether mainly pandora radio app. which is my go to app for music in the car. it does play spotify radio, have not tried other apps yet.
2. Hot/Cold. I live in the northeast where temps can range inside the car from 120+ to -20 very easily. I dont think the n7 will be able to handle the extreme cold or heat. especially the heat.
i love n7 and this setup.
