Car stereo and iPods
olasparov:
I see many car stereo in stores advertise on "ready for iPod". What does this expression mean here? An example: http://www.incarexpress.co.uk/view_product.php?partno=KDG421
You need a special cable to make this work.
To my knowledge it must be easier, better and cheaper to just buy a car stereo with USB slot (and/or AUX slot). Then you dont need another cable and the iPod presumably will also charge will playing. Here is an example of this kind:

Or am I wrong? Perhaps this player cant play iPods music just through that USB cable? Then whats the use of the USB slot then?
GodEater:
The USB cable kind would presumably just mount the iPod as a disk device. In order to be able to play the music on the iPod sensibly after having done that, it would have to understand the iTunes binary database stored on the iPod which translates the obfuscated directory / filename system into something the user could understand on their car stereo. Otherwise you'd be stuck with having to listen to random tunes that you couldn't identify until they started playing.
Of course - this wouldn't be a problem on a rockbox'd ipod with the music copied to it via drag 'n' drop :)
It also wouldn't be a problem on any other DAP which keeps it's files organised sensibly.
olasparov:
Well, did I say I dont use Rockbox on it?? Of course I am. Why should I then be asking this on a Rockbox-forum if I didnt?
So you think then it will be ok?
I have been presuming that one will play the songs from the iPod, meaning that one will browse the files and choose them from the iPod. But perhaps when using the USB it starts to change into just acting as an external harddrive? This might also be a major problem (when using Rockbox) when considering these audiosystems for livingroom where u put the ipod itself right into a slot and can play on a sort of stereo thing (http://www.apple.com/ipodhifi/ , http://www.alteclansing.com/product_details.asp?pID=IM7), since these are based on the iPod/iTunes self system. Then the remote and everything with the system wont work?
Of course its another deal when just using an AUX cable, but then you wont get the power charging as the USB cable does..

Whether you use Rockbox or not is neither here nor there. A lot of iPod owners that run Rockbox stick to using the iTunes method of transferring their music, and then use Rockbox's database feature to manage their music on the DAP.
I don't believe it would be possible to use the iPod controls to playback the music when it's connected via a USB cable - there's no protocol I'm aware of (Apple of otherwise) which sends music over the USB connection. This is only a feature when using a dock (and Apple's Accessory Protocol, which I'm sure I don't need to remind you, Rockbox doesn't support).
gnu:
Be careful! Many car stereos only support USB devices until 1 Gb: my car stereo won't mount my 2 Gb nano ...
Try it first, or buy a stereo with an AUX slot, or use a FM transmitter (that's what I do)
