Since Infill doesn't do business at the consumer level, it's not surprising that they wouldn't help you.
Hi I have a new audi tt and I'm intersted to buy one g4 but I want to use the steering wheel command to interface with g4.
G4 have a cable (brown) to connect to the steerring wheel, I have asked to infill in korea how to connect the cable or if they have a canbus adapter or if I can use a commontly in commerce can bus adapter, but they don't give me any reply so I think this ISN'T A SERIUS FACTORY
You will need to purchase an adapter through a normal car audio shop.
It's the same type of adapter that will be used for any other radio to retain the Steering Wheel controls.
There is a connector on the back of some G4s labeled steering wheel control. It is my understanding that connector is non-functional. It's not supported by the mp3car store so that is why we don't mention it as a feature in any of our marketing materials. There is a work around using a PAC SWI-X and a USB UART that would work with any car computer including the G4.
dear mr. Zip.Lock in a section of "photo and caratteristics of g4" in mp3car forum you can see this:
Here's a listing of the various wires out of harness:
Green/Black - Rear Left Negative
Green - Rear Left Positive
White - Front Left Positive
White/Black - Front Left Negative
Purple/Black - Rear Right Negative
Purple - Rear Right Positive
Gray - Front Right Positive
Gray/Black - Front Right Negative
Light Green - Reverse Gear
Orange/White - Illumination
Pink - Attenuator
Brown - Remocom - This is for steering wheel control
Blue - Antenna Turn On
Light Blue - Hand Brake
Blue/White - Amplifier Turn On
Red - Accessory
in the mp3car tha functioni is supported why you tell me that is not supported?
What year TT? I have done the integration work with the VW GTi for 06 and 07. It is pretty straightforward to get on the entertainment bus (comfort bus as well I believe) where these messages are. Then you simply need a peice of car connection hardware and some software...
my tt is of 2007 (mk2) if you can make a document to explain the operation we are very thanks in Italy
Document to explain?!?! Ha-ha, you guys are funny. I thought this was a car hacker's forum?
Seriously though first is the car connection piece. You need to connect to the bus. I will look through my docs but I think one of those buses is pulled through to the OBD port. The pins probably arent in the standard CAN wire spot so you have to run them from there to the pins your device expects them on. As an example normal 2 wire CAN is on pins 6 & 14 on the OBD port. But for companies that run multiple CAN networks to the OBD port you have to find those pins and run it to pins 6 & 14 on the device. As an example on newer Fords they run a second CAN network off pins 3 & 11.
Now that you have a device connected to the correct network on the car, the next trick is to reverse engineer the messages.
Once that is done, then it is a small matter of software to detect and/or send the messages.
I don't like to use these forums as a sales tool but when you get to the software peice, if you want something easy to use and program against email me.
