I finally finished the program to read the button presses on my Steering Wheel Controls. The complete story behind this and the instructions can be found here Most of this is repeated in the ReadMe file included with the setup program.
The setup for the program can be downloaded here
You will need DirectX 9 or greater to run this since it uses Direct Input. The MFC dlls it uses are included in the setup package.
If you want the source for this program (MFC / Visual Studio .Net 2003) e-mail or PM me.
This program was designed for and tested on a 2003.5 Infiniti G35 Sports Coupe w/ BOSE Sound System. It *should* work with any car that uses steering wheel controls that work by varying the current read on a power line when a button is pressed.
do you have pictures of the actual controls,
and is it for sale?
mobo $130 ; 150wOpus-$200 ; 256mb pc2700 -$10 ; 120gb HDD 7200-$70 ; Lilliput TS 7"-$265 ; USB LAN-Free AR ; Rikaline 6010 GPS-$34 ; ShuttleXpress-$37
Total = $746....Carputer = Priceless
Check the first link for g35 forums. Theres a picture of the cable there and how to construct it. You really only need to add a resister and diode to the cable and just hook it up to the joystick port. It will cost about $5 to make and require little more then rudimentary soldering skills.
I tested with my Sony X4S joystick remote...it works great, nice job!Originally Posted by god_of_cpu
This all sounds wonderful. Just one problem, my mobo has no joystick port! Is there any way to make this work via USB? Maybe with a joystick port to usb adapter?
Keep up the good work,
You can make it work with a USB to game port adaptor. You can possibly also rip apart a cheap USB joystick and try to tap into it's Analog to digital converter (the thing that the control stick is connected to) although I have never tried this I heard it should work.
Also, some motherboards have a header for a game port even though they don't have an actual game port, if yours is such a motherboard, you can just buy one of these

Thanks for the prompt reply.
I have a 2001 nissan maxima do you think that it would work the same? I have vol up, vol down, up arrow, down arrow, and source.
Also since ive taken my factory head unit out i dont really care about it being able to switch control between the radio and carputer. Is there anything i can remove from the diagram to make it easier since that isnt necessary for me?
