Usually when a car radio uses USB, it does not actually communicate with the firmware of a device, it just uses it as USB mass storage, in which case the only concern is the format and layout of the files.

Yes, that was my point.

I have tried it with my car radio + ubs but it didnt work.
The radio couldn't deal with the amount of songs on the ipod.
I think there is a limitation of 256 songs.

Maybe a more expensive car radio does work.

Most more expensive decks use the ipod connection devices. The ideal route to go atm IMO is to use the line out and connect it via rcas.

It didn't work at all. The ipod just kept spinning, but nothing happened.
I waited for about half an hour... and then decided that probably it will not work.  ::)

I tried something similar using a JVC mini stereo system with USB host.
I connected an Iriver H140 and the machine analysed it for 15 minutes before
playing the first song. Navigation was only by song number - pretty useless.

I'd not use something like this in the car with any hard disc based player:
Normally, they do not spin down the hard disc, so they will drain the batteries
very fast. Also I do not feel safe if the HD spins all the time while driving.

USB-Host might be useful together with the 1 and 2 GB Ipod nano. I'd not use
it with any other Rockbox Ipod.

BTW, there are some JVC car radios that offer a line in on the front panel.
If my current car radio cassette player breaks down, I'm going to get one of those.
