Galaxy Tablet - car application

[Inspectre]

I have an idea to install a Galaxy tablet into a car without a head unit- idea is that it will be used for music, sat nav, phone, rev camera etc - just looking to see if anyone has done this and experience to share or if anyone has any pointers - ie how do you connect amp etc

thankyou, Mark
