Hi,

I'm just getting into this carputer stuff and i'm really interested in the obd side of things. Just wondering if anyone knows where I'll find the OBD port on my 2003 volvo s40.

I've searched the net vigorously with no result so i thought id ask you guys?

If it is sold in the US it will be somewhere near the steering wheel under the dashboard. Look for a parallelogram appearing connector that is about 2 or 2 1/2 inches wide and 1/2 inch tall.

I'm not sure, I had an older volvo (850) and I believe it was under a change tray.

SwedeSpeed or Volvospeed may be able to help you out. Turbobricks is good, but they focus on the older RWD turbo volvo's.

I had to build a CARPC setup into an 09 Mercedes GL450 with a MOST network. I used an aftermarket amplifier and ran the speaker wires to the stock amplifier location and tapped into the car's speakers there. When I removed the head unit I did not lose any AC functionality b/c the two are separate systems so i don't know what to tell you to do about that.
