Im new here and I'm looking for a possible touchscreen to install in place of the current headunit in my 04 Mazda Tribute. I have been doing research and I believe it has a double din slot? I don't paticularly want one of the motorized ones. I'm looking for something that will slide into the area where the head unit is currently located and have something close to a 7'' touch screen on it with a VGA input to run a carpc into. I'd also like it to be able to run my audio system(speaker outs) and have the possibility to be GPS and wireless internet capable later on. But that could be achieved through the carpc i guess.

Any Suggestions?
