Rockbox Interface With Car Stereo?

I've been using one for a long time and there doesn't seem to be a problem for me. But yes, I do agree that relying on the head-unit to scroll through 4k + songs is more than a tad ridiculous.
Alright, for everyone, let me rephrase the question that I had specifically. I am VERY anal when it comes to sound quality (I have a $1,000+ speaker system in my car, not that factory shit). My original question should have been much more specific.
To my knowledge, for 100% transfer of an audio file from the iPod to the car stereo, there is a 0% loss. I KNOW the stereo can lose some audio quality and I KNOW that the speakers can lose quality etc...etc...
That is not what I'm asking, though. I just want to know if a line-in audio jack from the iPod to the cars 3.5mm headphone jack will result in a 100% transfer of music quality. There is NO reason for me to have such an expensive system in my car if I'm going to lose 10% of the audio quality right at the jack, you know?
I'm sorry if I sound like an ass, I really appreciate all the responses so far, honestly! I should have made my first question just much more specific.
Thanks again for all the responses so far and for continuing to put up with me. ^^

The line out will lose 2.958774% of your audio quality.
Seriously, this is an impossible question to answer. If you want to use Rockbox in your car, then a line-out/line-in connection is the best way to go. As long as you are using a decent cable that is not unreasonably long, there should be no appreciable loss.
NeoDestiny:
No no, it's not impossible to answer at all. From what you say, then, there should be no loss in audio quality. I wasn't looking for an exact answer, I was just wondering if there was a loss.
The question is comparable to someone else asking "If I convert this FLAC file into an mp3, will I lose any audio quality?" Of course you can't give them a specific answer, but the answer is, most definitely, yes.
But, from what I can gather from your sarcastic answer :b, it sounds like there should be no loss in audio information, so thank you for your response.

You suggested that you wanted an answer that gave information as to how much was lost.
Being an analog signal it is an absolute certainty that some will be lost. Whether you can hear it in a car or not is a matter of debate, odds are very good it will be impossible for you to hear going from line out to line in, unless you've got a particularly shoddy receiver or cable.
He answered that way because you were giving numbers, and it's a given that an analog signal is imperfect, though not necessarily so in a manner that you can hear. Someone who's spent this much money on expensive audio products should be aware of this fact without having to be told, so the assumption was that you were aware of it and wanted input as to how much might be lost, rather than if any would be.
NeoDestiny:
I'm aware that any amount of transferring of any signal to anywhere will result in a loss of audio quality, of course, but that amount is so miniscule that it is irrelevant (as opposed to converting a file from a higher quality lossless codec to a more compact one). I was just wondering if the loss when using an audio-out was a significant one, but it sounds like it's not.
Thank you for the answers!
