Hi Rehan, you have figured out most of the things, you just need to piece them all together. I've attached a layout of my carputer setup. Its almost a few years old but things have not changed that much. The price you quoted (50k) is more than adequate enough for the project. I'll share some links later that would tell you where you can buy all the hardware from. I personally source it from China, have a few vendors there that we do business with regularly so i kinda use them.
The sad part is that the locally available Chinese 2 din boxes are absolutely no good. The Win CE part is handedled by a samsung 500 mhz mobile processor with 1 only SD card port. All media/radio/video is handled by another board on the box. I wanted to activate internet on one of these boxes, imagine my surprise when i noticed that WINCE had no connection to the USB or other inputs available in the box.
So, i suggest you leave that aside, or better yet sell it a good price and use that money to get a 7 or 8 in VGA touch screen monitor.
Alternatively, if you wana spend some serious cash, you can get a WIN XP (Atom based) system with OEM fitting for Corolla. But those cost around 300 to 400 US $ excluding duties and freight. OR a simple 7 or 8 inch Win XP Atom based tablet???
I would be more than happy to help out.
