Okay, no doubt a few people have mentioned this already, and with good reason, it's a great project. For me the biggest problem is the screen, for two main reasons:
1. Screens are expensive.
2. Screens are not easy to fit to cars, especially if you don't have a double DIN space.
So I had a brainwave, and this is what I am here to discuss. You can check out the video (it's less than 3 mins) to see a non Pi version
In a nutshell, I plan to use a mobile phone as a 'remote' and put the R-Pi and Wireless board behind the dash, wiring it in to the existing head unit. Then I do not have to worry about a screen, simples
So, this raises some questions for me, mainly about the OS.
How will the R-Pi versions of Linux cope in an auto environment where they are being powered up and down a lot? Would a battery backup be required to give the Pi time to shut-down when it senses a loss of power (ala Powerchute)?
What is the best way to collaborate on a project like this? I think posts like this will get lost over time as they get demoted to page xxxx.
Thanks for listening,
