Default IPOD Interface

I take delivery of my new S4 in a couple days. I have seen the on-line tutorials but still have some basic questions. Do I have this right...the MMI after the IPOD input is selected, will work to select music on the IPOD? Including the IPOD shuffle feature? That seems great, put 160 MB on a $200 IPOD and let it sit in shuffle for months. Am I missing anything? Thanks, Alan

If you got B&O sound, use SD cards.

No you are correct, I use my Ipod just that way. Too lazy to transfer 6000 + songs to SD cards. Only bad thing is that the shuffle feature (called MIX on the MMI) tends to turn itself off after the car is turned off for 5+ minutes and has to be turned back on again every time.

I have had not problems using the mix or shuffle feature through MMI but still get weird volume fluctuations when skipping to the next song. Occasionally it will drastically increase the volume for a split second before the song cuts out and the next one starts, other times it will significantly lower the volume before ending the track. I think this was discussed on a previous thread but I do not know if any correction was found. It's not a major issue for me, just a minor strange bug.

IS the SD card alternative what is being referred to as the "jukebox"?

Yes, the SD cards sound better. The iPod sends some type of analog signal that gets upconverted to digital or something like that. There's a thread on here that describes it much better. The SD cards keep the signal 100% digital which helps them sound better.

To clarify, you can use the iPod as you've asked about, or you can use SD cards, or you can use the jukebox hard drive that is in the dash. I read one or more posts that may lead someone to believe SD card = jukebox but they are different. You would need an SD card to copy songs to the jukebox unless you get a VAGCOM cable and enable CD ripping to the jukebox via MMI. I haven't tried ripping CDs--just as easy to me to drag and drop MP3s onto the SD card and then upload from the SD card to the jukebox. So far, I think the jukebox 'loads' faster than the other two options but I haven't put a ton on the jukebox.

Regarding quality, the iPod interface converts your digital tracks to analog and then back to digital before playing over the speakers. Some feel the quality is less because of the conversions. SD cards and the jukebox will not convert from the existing digital format to analog and then back, only the ipod does this...because of the iPod interface cable I guess. If you want even better quality than all these, play a CD with full WAV or other compatible format, or play DVDs. If you get a VAGCOM cable or get help from someone who has one, you can unlock the MMI screen to play Video In Motion (VIM). Not legal, but pretty cool.

I didn't check what type our stereo system is and I might be wrong, but I think music tracks are converted to analog signals inside iPod, conveyed on the cable, fed into MMI analog input, got amplified, etc. they need not go back to digital form to be accepted.
Some said the music from iPod being inferior. I believe it just has to do with the iPod's build-in DAC and the thin gauge of the cable used.
However if it's class-d amp that resides inside MMI, it will be totally different story.

The best non-cd quality is to rip CD's into an SD card in AIFF format (which you can do with ITunes) and then plug the SD card into the car or fill up the jukebox. Downside is it takes a lot of space.

I have spent a good part of my adult life in 2 channel tube amp audioville and I am not convinced the AIFF vs. MP3 format will make that big a difference in the car; especially from an image and depth of soundstage point of view considering the inevitable road and exhaust tones but am picking up my new S4 today and will experiment and report back with my opinion.
