Okay guys.
Its been a while, but this was a fail.
The only reason being that windows 7 is NOT supposed to be run as the OS, first time the car shuts the PC down completely, it goes into restoration mode and then the PC doesn't turn off, this is a huge problem. So I removed everything from the car, replaced the original stuffs, and now selling the 318i.
I am back at the drawing board with the OS, need to find a proper OS that can run, never go into safe mode automatically. Im thinking winXP, but I am not sure if USB 3 will work then?
The new system will go into the 330i. I am currrently using multiple devices in the car, ipad 3, note2, and garmin, so want all of this in one.
PLUS: DONT MAKE YOUR OWN FACIA, BUT ONE!. Trust me, it looks good, but if you are like me, you will find small cosmetic problems very quickly and it WILL irritate you.
The PC will go in the car end of next month. My plans are the following.
Take out the seats, take them to be refurbished, while they are out, calmly put in the pc.
Also, the casing will be replaced by something way smaller.
