You can start transmitting yourself but there are pitfalls depending on the interface implementation. Being BMW IPR I'm sure that there are issues with people disclosing information, though there seems to be information in the wild on some Beemer forums. Harder is deciding what all those bytes mean. Connect your adapter, set your baud rates in hyperterminal or similar, and just watch the traffic go by. If you want to pick up the messages, you can do it anywhere on the bus. I have an i-bus to rs232 converter - yet to be used - and if I just plonk a terminal emulator on that do I just need to capture the strings as they appear or do I need to send any queries onto the bus? Personally I am interested in where you pick up the i-bus from (physically) and how do you intercept (and store) the messages. Jim - if you say you are writing the i-bus messages to text files, then shouldn't your win ce system simply read from the files and display accordingly? or is what you want more complex than that? If anyone has a lead on a an app that can do this or would like to get involved in writing one dont be quiet. If that can be done we have a digital dashboard for the R75. What I need is now is a WinCE app that can read the data and display it. It also makes it easy to test using the emulator. I can get the microcontroler to interface to a USB host and emulate a flash drive easy enough. This way it can just overwrite each file file as data comes in. A hardware adapter is needed to interface a personal computer's COM port or USB interface with the vehicle's I-BUS.

IE all files in one directory, filenames = decoded data, File contents = value. Navcoder is a shareware software utility available via the X5World navigation forum allows the navigation computer to be re-coded in vehicles that use the I-BUS communication system. For ease on the microcontroler using a seperate file for each decoded string. This will decode the I/K Bus data and write the decoded data into a file. To do this a microcrontroler will be attached to the I-Bus.

My idea is to pass the I and K Bus info to the Avic using a group files via the USB port.
#Using navcoder with e39 how to#
Now I have figgered out how to run apps on the AVIC I would like this to be on the head unit.

I was going to use an lcd with this to display things like Coolant Temp, Voltage, power output ect. I aslo added some winCE games.Īs a seperate project i have been fooling around with decoding the I-Bus and K-Bus data. Updating the maps activated activating sauna traffic in Sydney which Pioneer wont relase till late this year. So far I have added things like new maps and speed warnings for school zones.

This way I dont have to update the AVIC to test.

To make things easy I am using the MS WinCE emulator with image of the Avic on it. I have been playing around hacking the Pioneer Avic-F900BT.
