Thread: Someone here has be be able to crack this HDRadio for the car!

also impressive work to get it all working in a matter of two weeks from the time you got the hardware...

Thanks.. i took my time planning during shipping..

Also to confirm i have tested this in the car in a moving environment.. the radio remains stable and sounds great.. Listening to AM in HD disturbs me.. i was listening to a hockey game in stereo..

so all i would need for this to work is....

the reciever

an ibus to usb from here

and your software whenever it is ready? coorect me if im wrong... im thinking in my head how im gonna hook this all up when its ready to go..

correct make sure tell them that its for a 2003 3series
.. the software will be for the Roadrunner front end. you will also need a 10k ohm resistor from radio shack.


the hookup is not that hard.

thats even better since RR is my front end of choice, plus being an electrical engineer student.. i think hooking up a 10K ohm resistor should be something i can handle

So with your software, you will also be able to control an ipod as well?

I read somewhere that there is weather information laced in RDS... see anything like that?

And FINALLY- Can you find a way to record HDRadio to the hard-drive? Better yet, use the RDS information and have that translated into an ID3 tag, or filename for the audio file? That is my ultimate goal, and you have just opened that door.

Thanks,
Rock

First of all let me clarify.. i am using already created software called Ibusrr or Ibuscomm. I dont want to take anyones credit

Now for the good stuff. I am certain that we can create some sort of recording feature but i would like to get full functionality first.


You will be able to fully control your ipod with this unit using the optional ipod cable as well as an AUX input.


Right now i am building a test skin to control the radio from within RR.. right now i have a nice hex filled screen with tons of raw data. Once i get the screen wokring fully i want to develop 2 way communication to display the RDS information.. I am a hardware guy so if anyone (HINT HINT!!) Could possibly help me code some software it would be greatly appreciated

are u serious..i should order the one for a 2003 3 series or is this a j/k that i didnt get...its that smiley... cant tell if you are serious or joking ...

Yes, and since you have asked several similar questions, let me give you the low down.

Every BMW since, I believe, 1990 or so (I might be wrong on the year) uses something called the I-Bus to communicate between modules and systems. It uses the I-Bus when you press a button to unlock the doors, the door module sends a signal along the I-Bus to the lock module, which opens. THe CD changer communicates with the buttons on the radio through I-Bus. The diusplays gets thier information over I-Bus. EVERYTHING happens over the I-Bus.

The I-Bus data has been decoded, and has been for several years. With the I-Bus, assuming someone wanted to "do something" say, emulate a CD changer, they can develop something that reads the CD controls from the I-Bus, and send the appropriate information back over the I-Bus to the car, so that the car thinks there is a CD changer. This only requires an I-Bus encoder/decoder, and the proper programing.

This HD radio was created for the BMW's with I-Bus. It connects to the I-Bus, and communicates with and over the I-Bus. What they have done here is, using an I-Bus encoder/decoder, connected to the computer, decoded the information that goes over the I-Bus for the HD radio to work. They then, I assume using the instruction from the HD radio, monitored the buttons (although, there are libraries of which codes are sent with which button push in the Bimmers) to determine which codes are sent, and how the HD radio responds, so that they can program a computer to send and recieve the proper codes through the encoder/decoder to the HD radio.

Hope that explains things a little.

I think it was 95 onwards, and that it started with E39s 'cos it was bm's flagship, till 6 series came out.
