It's a pretty simple deal to splice into the fibre optic loop. And for this you shouldn't have to need to program via Tech2. It has a switch: control either the 500 OR CD. It will simply route the steering wheel signals to the 500 or the CD.
Except...I thought those signals travelled via the CAN bus instead of the FO bus.
Now, this will all be well and good, except how do you get it to default to aux-in when you turn on the car?
Not quite that simple.
The system will need to be added via Tech II, as it probably simulates a CD Changer. Unless it's added, the ICM won't give you a menu option to control it unfortunately.
Steering wheel controls will not be an issue, as these work properly with the trunk mounted CD changer anyhow. The are converted to Optical commands sent down to the trunk by, you guessed it, The Holy Master of Infotainment, the ICM.
If the system is really clever, expect the following:
1: Select CDC which will bring the 500 online.
2: Select Change Track, which pulls up the CD-Text display of track names.
3: CD-Text display will display a scrollable interpretation of the Ipod menu, i.e. Playlists, Album, Artist, Track etc, where you would normally see the CD-Text displayed. This would be done by spo ofing (Stupid bloody censorship ********!) the TOC data sent from the CD Changer to the ICM on the SPDIF lines.
4: Selection of one of the above will make the system enter that "menu" (normally it would select the track to play!) and then you will have to go to Change Track again, to be presented with the appropriate list for that menu entry. The same will be repeated for selection of deeper levels. I would expect you to be able to hit a key on the numeric keypad to return to top level or higher level menu's (1 for Top Menu, 3 for up one level for example)
If the system works this way, then cool. If a later version of the system works this way, please note I am looking for a contributors fee!!!!
