I am "in process" on doing this installation. As my CD changer decided to die on me, I thought I'd replace it with an iCruze/iPod installation.
I managed to get the setup to work plugging it directly into the head unit using the recommended IC-HND1 adapter kit (though the Monster instructions were wrong about which cable to use for the '99 stereo
). It appeared to work pretty much as advertised. The program button selects the next playlist (supports 6). The previous & next track buttons do just that... I didn't play with it much beyond that.
Unfortunately for me, I'd rather have it installed in the trunk so as to take advantage of the SmarTenna system I have installed. I modified one of the included cables (the one that I can't use) to match the pin configurations from the head unit to the iCruze, but it didn't work. I assume this is because the wires from the head unit to the CD changer are not straight-thru. The project for the coming weekend will be to rip the head unit out again, and verify the pinouts on the changer cable (which I was really hoping I wouldn't have to do). :frown:
