So I see this YouTube video about how it's possible to use an iPad as a stereo replacement and a cheaper alternative for a video player and dedicated navi unit. I know this would require some extensive modification to the stock dash, and hopefully the climate controls would relocate to that recessed tray, but I just happen to own a 2nd gen iPad 16GB wifi model.

I'm willing to do this and I have the cash to lay down to have a local stereo shop hack everything to put it in and make it look factory, but I wanted to do this thread as a feeler to get opinions from others before I pulled the trigger. This option is especially tempting to me because rather than buying a 600-1,000+ dollar double din headinit, I could reincarnate a hardly used iPad in my car as a more cost effective option for video and nav. To make it able to access data for Internet radio, I could get a wifi hotspot box or similar through my cell phone provider and set it up in the car. For nav, I could purchase a quality nav app and have turn by turn nav. I am unsure how I would take calls through it though. Ideas on that?

Yes? No? Opinions?
