iPod 5.5 and my car kit

An "older model" would be, say, the Firewire-only iPods - the iPod Video is pretty late by our standards :)
The website for the unit suggests it can load music from normal USB storage devices. So, this is probably another instance of a case which has come up before: because Rockbox uses the same USB device IDs as the original firmware, the head unit thinks it's an iPod and expects to use the special iPod protocol to browse the iTunes database. If the device had a different device ID it would just assume it was a normal USB flash drive and would browse the filesystem directly.
It's not particularly difficult to change the USB device ID Rockbox uses; there's a patch for it around somewhere. If you did that it would probably work fine. We don't really support this because it's kinda.. hacky. The USB-IF don't like people using USB IDs that don't belong to them.

Oh, I see! :)
You're correct about it being able to load from USB devices (in fact, I have tried it). I saw the thread about changing the USB ID, but I didn't realize it also affected the manner in which the head unit would try to talk to the iPod directly. What you say makes sense.
I also was hesitant to try it for the reasons you mention.
Is there any chance that the serial bitrate (currently set to Auto) would affect compatibility? I didn't tinker with that at all.
One last thing, perhaps it makes sense to update the iPod accessories Wiki to show the Parrot as (mostly) incompatible? The charging does work.

If you have the time to document your experience it would be much appreciated.

Understood.

It's perfectly safe to try it; we don't want to do it *in the main build* because of potential compatibility issues and potentially getting "in trouble" for using someone else's USB IDs (since we can't afford to pay to have our own), but there is no actual technical risk to it; feel free to try it on your own player. Even if you screw up Rockbox's ability to connect over USB completely you can just go into the Apple disk mode; ipods are unbrickable.

No, that's not going to work. The head unit is not connecting to the iPod as an accessory at all, it's connecting to it as a USB device which doesn't use that serial bitrate.
