Carputer confusion- n00b needing help
I have thought about putting a carputer in my Landcrusier, well I started reading about them and that is where the confusion began. My main concern is that I will buy the incompatible items or that they will not do what I want them to do. I have done some research and even tried to call the few places out there that sell the items and no one has returned the calls or emails. One problem is that I am in Australia and all the car and audio installation people are asking for wiring diagrams. I would do this myself but I have NO IDEA how to wire things to my car, I prefer to have a professional do it. As far as building the computer I have no problems as I built my home computer myself, so that is not an issue it's just connecting it CORRECTLY to my SUV.
Now for the main issues: I want Sat Nav, Wireless internet connection (@hotspots), possibly to start my carputer when I turn the alarm off and turn it off when I turn the alarm on (I have read that if you don't get complete power disconnection you can have a dead battery). I would like to play my iTunes through the carputer and dvd's along with some other programs possibly.
Now as far as the carputer itself I am totally open to all possibilities but I have been told the power supply is very important. The screen I have been looking at is a Lilliput double din touch screen ( as this would replace my standard radio )
I am concerned because I am not able to get a reply from any retailers that if I order online I may not receive my order than I lose that money and I can't talk to them so I have no recourse. I would also like ot know if it is possible to run bluetooth through a carputer for my phone.
Thanks for the help.
