Units ordered..
Can anyone get the pin out on a BMW 3 series without DSP.. i need the 6 pin harness that goes with the CD changer.

the 3 pin wire is the IBUS wire..

For the 6 pin wire i can only assume its 12V, Gnd, L+, L-, R+, R-

I just ordered up the parts also, so I'll help contribute as I can, I am not a programmer, but I'll have the parts, and I have access to a friend's Z3.

Oh yeah, no HD stations in my area, so I'll be interested to see how the unit deals with the analog stations.

$280 to listen to radio on a carputer, more than the HCQT, but someday we'll get HD in town!

Dave, where did you order the ibus usb adapter from?

Many thanks sama.

I have ordered everything as well.. Once we get it working all we need to do is get the button codes down and get it implemented in to front ends.

good we can work together.. we have the same parts. I ordered it directly from reslers web site.

DICE unit will have the 2 harnesses..

1. 3 prong which we will have to connect to the reslers adapter and also splice in 12v+ and GND

2. 6 prong which will have 2 gnds which i dont thing we need and the R and L audio.

We have the button codes figured out.. now we need to find a way to get the Data from the radio station to the display.

Anyone here wanna help with coding? Im just a hardware guy!!!

Creating some logic buttons for front end integration.. we can translate the keypresses into Ibus code later..

According to the manual i created some "macro buttons" i think we can use

FM Manual tune button:
Sent CD Init String
Wait for response
5>>>>>1
Use < > to tune

FM Seek button:
Sent CD Init String
Wait for response
5>>>>>2
Use < > to seek

FM Preset 1:
Sent CD Init String
Wait for response
5>>>>>4

FM Preset 2:
Sent CD Init String
Wait for response
5>>>>>4>

FM Preset 3:
Sent CD Init String
Wait for response
5>>>>>4>>

AM Manual tune button:
Sent CD Init String
Wait for response
6>>>>>1
Use < > to tune

AM Seek tune button:
Sent CD Init String
Wait for response
6>>>>>2
Use < > to seek

Ipod Button:
Sent CD Init String
Wait for response
1

Aux In button:
Sent CD Init String
Wait for response
5>>

No need! There has already been much work to integrate ibus into RR. Recently Warified (I think that's the user) did some work on sending commands to the ibus from RR, and Enforcer added support for this in his iDrive skin. That, added with ibuscomm's ability to send RR commands via COM (look at how it sends next track etc), should give you bi-directional communication.

I know we have the interface.. but i guess we need to figure out the skin commands to use to display the feedback. Such as RDS data and the channel it is currently on.

Since we are using the car pc i also noticed that we can change the display of text. If we set CD-6 to track 3 which is the nav output setting we can set it to display the extended rds and digital info.. up to 20 characters rather than the standard 8 or 12.
