Hello, I'm trying to mod my car's cd changer to use my ipod as the audio source. However, when the cd changer goes to the next track or disk, there is an audio pause. How can I make a blank 70+min audio CD to get around this. Or better yet, how can I make a disk that never ends, or skips back to somewhere previous on the disk without making a change in track. So that it never goes on to the next disk.

I guess maybe I can scratch the hell out of the disk so it just keeps skipping, would there be any harmful side effects to that?

Would't an FM tuner be better? my friend has the mini tuners and it works great.
Are you kidding me? Better? Yeah stupid little FM modulators are sooo much Better than direct line to stereo.

Duplicate the files to get as many minutes of silent tracks as you want, drag 'em into iTunes and burn.

Does your CD player have a repeat disc/track mode on it? That might be the easiest way to produce eternal oblivion.

Thank you, wonder if I can scratch a silent cd to skip over and over

Your head unit would probably display a 'disc error' after a while and give up.
 
I don't get it. If you have a line in on your stereo, don't you have an AUX button or something? Why do you have to play a silent CD and then have the iPod play over it. Why would they put the line-in if you had to do it this way?

That's the problem, not many do. At least not many that i've seen.

From what I read about CD Changers and car stereos, there's usually an audio connection and a data connection from the changer unit that both connect to the head units line ins and some sort of data port. You can easily plug an iPod into the line in but not the data port. The head unit will only play the audio coming into the line in because it thinks its controlling the CD changer. You can connect an iPod to the line in and when the head unit thinks its playing a CD it will in fact be playing audio from the iPod. CD's will be playing in the CD changer whilst this is happening. When the CD changer tells the head unit its finished playing a track, the head unit will pause waiting for the next track to start. This is what causes a gap in the audio coming from the iPod.

The original posters idea is to create a CD filled with 1 track thats continuous, so the CD changer doesn't ever send a signal to the head unit telling it to pause.

I think i've got this right?

Thats exactly right, and I'll probably just make a long track of real audio, and then try to scratch it so it loops forever. If not, then just make that blank CD. Technically there doesn't have to be silence, just needs to be continuous, if it is silent then I wouldn't have to put a switch in it, but I'm going to anyway while I'm in there. Run a 12V power to the glovebox, and my belkin recharger with line out audio, all neat and tidy in the glovebox like a better looking BMW.
