When is a project really finished?
Now, after 3,5 years I consider my project finished even though I have ongoing projects to improve on the system, as the hardware is installed as I want it to be. I must say that I have been longing to enter this thread :-)
Everything is described
in detail here incuding links to some youtubes and ongoing updates.
Edit: Properly sized pics

Some kind of overview

All the stuff on the floor before install.

Left wall in boot

In detail. Here is where the CD changer used to be. The Powercontrol and GPS unit is of my own design to make the system be as much factory as possible.

The isolators for the HQCT etc closeup.

With upholstery in place

PC and power amp

PC baseplate

LC-679 with T7100 dualcore cpu, 1GB RAM
64GB Samsung SSD
M2-ATX Power

Everything in place

Rearview Camera

TV antenna. I also use BMW GPS antenna.

The Bordmonitor before I put it in the car.

This is what 4x better resolution does to picture quality

BMW MD headunit replaced with Bordmonitor with USB DVD and 6,5" VGA LCD panel

Here is tyre pressure unit, USB hub, OBDII interface and HQCT radio

USB connector at dash

I put in a standard BMW mic next to rearview mirror

I had to build a special interface for it, as it is powersupply and audio in two wires only
Thanks for all the help received from this forum!
