It's all software running on a computer. I can do anything I want with that.
I worked in a car audio install bay for over a year and have done at least 200 installs, and a dozen or so custom jobs such as the one I'm doing for myself. I have never had a single complaint.
It's basically going to look like this when done, except it will be a touch screen and will not have any buttons on it. I'll put the toggle switch to turn it on/off on the steering wheel.
