Thanks. I intend to use the serial port for HD radio, but was willing to toss that for the ibus interface, but I feel much better about getting the USB version.
Got mine working finally! You do need to power the interface it turns out.. no matter whether it's USB or Serial.
As for which one. It really depends which PC you're going to use. If you have serial port, you can get the serial one. If not, get the USB one.
The USB one is just a USB/serial emulator anyway, so it should work with any setup.
I went for the USB one as it means I will always be able to use it, even if I change my laptop in the future and only have USB.
Thus I will have to save up and get one maybe in July...
Ha ha. I better get mine before the US dollar falls through! I wish you luck on your carputer. Hopefully you will document your build that I can use to help build mine!
I've asked a similar question in the e46fanatics forum.
See the whole thread here.
Here's the rundown from post #5 over there:
- Would I be able to control everything listed in the IBus (and more) with connecting to the KBus?
- If so, what's the best way to connect to the KBus? GT1 DIS? P.A.Soft? Carsoft?
I have a massive system in-place, I am also busy programming my own software for it... and awaiting the IBUS interface so I can connect it and take pictures: My setup is not done until I get this IBUS interface
Maybe someone can ask Rolf nicely to send me a USB one for charity... - also I will be able to use it as research for the development I will do for this unit inclusive (as I am from a developing country - 3rd world, but lately with all the power cuts we seem to be leaning toward 4th world country ... haha)...
I will pay for postage... hehe
i have i bus in the head unit on old round pin 7 which i extended to trunk via
a) separate wire or
b) used an unused head unit to amplifier wire since i completely replaced the stock amplifier with 2 channel amplifier (therefore don't need seperate wires from hu to amplifier for rear and front channels)
now i bus interfaces works.
