sweet.... keep it moving... i like the harness thing - nice alternative
By the way, this is the menu screen I customized for ICT. I found some problems to configure CENTRAFUSE so I will start with ICT that it's so simple that it rarely fails.
That is nice.
Simple and evrything you need on one page.
Needs a little tweaking in the appearance department, but on it's way to an awsome interface!
At last I've got the PC installed and working. I only have to configure a couple of things (TV and POIs). I'm working on a post to describe the custom harness and the way we connected that it's the key for this project and I'm sure you will apreciate.
I opened two blogs to describe the project. One is in Spanish and the other in English. Both are still under construction because I must upload the photos, but the whole process is already posted.
As everybody knows, this is the main issue for this project. Mbai2 was too heavy to me and using a FM modulator is not a good option so we decided to make a custom harness to make it possible. Thanks to my friend vwcooper, who made it happen.
The first thing is to get a high enough level of sound from the PC so we used a minijack to RCA cable and plugged it to an ALPINE 2 channels amp, small enough to be located behind the climate control. Two channels is enough because the factory non-Bose system only provides right/left output.
The whole system is powered from one of the empty fuses at the box under the backseat. The cable (+) goes to 3 different fuses we located under the foam at the gearknob room.
The Yellow one (20A) is to feed the new amp.
The Red one (10A) is switched to turn on/off the computer.
The Orange one (5A) is switched to commute from one audio source (factory radio) to the other (computer).
To commute the audio sources we used two parallel 8 pins relays, so when the switch is off the speakers receive the audio from the factory radio and when it is on the audio comes from the computer.
Summarizing, the circuit is closed as follows:
All the outputs from the factory radio (ISO) are positive and they get to the 8pins relays (that receive the signal from the computer as well and are switched by the button at the central console) and then to the factory amplifier (ISO).
If you are using a bluetooth hands free device to answer your phone calls (I have the Parrot 3100), you must put its ISO between the relays and the factory amp, so it will mute the audio no matter what source is in use at that time.
When I purchased a factory radio to assembly the computer without even touching the original one, I didn't know that we should have to go to the dealer to unlock it from the THEFTLOCK message it shows when is connected.
The took € 80 away from my wallet for a 5 minutes operation but I was not able to find anybody with a Tech2 tool to be connected to my OBD II port.
Bad luck having an american car in Spain ...
For those that are not sure where I located the camera, have a look to these pictures.
As you can see, european plates are different. The thing is that it's originally located too high, so we must put it lower to get room enough for the 3.5 cm diameter of the camera.
To avoid anyone touching the camera, I placed a black PC sheet and then the plate.
