I originally started this post before having a lot of time to study and test the system and features.
I now have spent time looking into some problems and I had the opportunity to use the system during a roadtrip from the San Francisco area to the Seattle area.
The controls from the head unit are adequate - but not great. :( I suspect this is because things are limited by the fact that the head unit is expecting the iPod to be a CD Changer. For example, a CD will not have more than two digits to display the track number on a disk (it would be difficult to get more than 99 songs on a CD). An iPod however can have hundreds of songs. This means that sometimes the radio'* display and the iPod'* do not correlate. There is a limitation as to how the head unit displays what IT
thinks are disk and track numbers. Since there are these kinds of limitations, it is possible to "confuse" the iPod/head unit communication. The result is that there are times when the iPod will need to be controlled directly (rather than the buttons on the radio or steering wheel).
There is a bigger problem though.
The iPAC-OEM was apparently not thoroughly tested in an actual car.
When I use the turn signal or turn on the headlights (or other high draw electrical item), it completely messes up the sound for several minutes.
I suspect this is due to a poor design to separate the analog and digital grounds inside the iPAC-OEM.
It is intolerable.
It is also unfortunate because when it works right, it works very well.
I have done various tests with pulling power from different places including a completely separate battery. All to no avail.
My next test is to wire the analog audio from the iPod, completely around the iPAC-OEM.
I will be heading back to California on Tuesday and hope to have it working to test on the trip back. Look for another report...
