Just spent most of this afternoon putting a lot of music on to 2 no 2gb Sd cards thats about 60 albums should be enough for a few weeks saves having to carry all those CDs. Didn,t see the SD Card slot on the stereo till Friday morning. You learn some new every day with this car:D

The slot is only on the basic sound system. If you go sat nav you dont get it.

Audi really do know how to add insult to injury, don't they. So you fork out almost £2,000 for sat nav and no SD card slot? I assume the CD changer still supports MP3 on CD ... or are you forced down the AMI route at an extra £200 plus connector cable?

:( ah ok this is why i dont see it then.... i have the sat nav package with ipod connector.

I dont have the B&O system :( but i have the bose system :) which im happy with

You may not get the sd slot but you do get increased DSP options on the B&O with the nav along with a 6 CD player. so they giveth with one hand and take away with the other.

you have the 6 cd changer which gives you a different unit (sat nav automatically includes the 6 cd changer as well).

So, in your case you neither have the slot or the extra DSP option.

FWIW, I posted on another thread that I've run across several reports on a German forum of folks who are successfully using 4GB SD cards (even though the owner's manual apparently indicates only 2GB max allowed).

just to let you guys know the MMI fully supports the SD card information listing all tracks, artists times etc. There was some confusion on another thread. Sorry if this is old information

Can anyone confirm whether the system will play apple format tracks i.e. itunes from the SD card or is it just windows media player files ?

Hey guys, I think there is another thread on this SD card question that I started a couple days ago without knowing about this one (sorry). My question was - for those of us with NAV, there is no SD card slot, so I asked if anyone had tried to use the glove comparment cable options (USB cable) to a hard drive or SD card adapter - TXcarguy responded to my thread saying YES it works fine. So, for those of us with no SD card slot, there is another solution. Order the optional USB connector cable and tuck your SD card in your glove compartment and you are ready to go. I am in the computer business so I plan to install a mega-size hard drive in the glovebox with ALL my songs - cool.

USB -> hard drive works

Hi guys

I bought a portable hard drive (Formac 250GB) last week and can confirm that it works well in an S5 with the AMI -> mini USB cable. The cable was overpriced at £25 but I couldn't find anywhere other than an Audi dealer who had it! I believe there's a mini and "normal" USB so order carefully.

I've currently got around 7000 MP3 converted as Lame -V0--vbr-new (~230 kbps) on my HD and they sound very good through the B&O stereo. I've saved my MP3s as "Artist\Album\nn song name.mp3" where nn = track number, so it's easy to navigate the directory tree. The only (minor) things to note are:

- playback is NOT gapless (there's silence between one song and another) so mixes and albums where the songs merge/flow are interrupted (and this is with Lame gapless info, so it's the stereo not the MP3s)
- it can take a while (5-10 secs, guesstimate as haven't timed it) for the display to show files in a "full" directory (i.e. where there are many (hundreds) of files/subdirs) and become ready for input: this makes going "up" from album -> artist -> ALL artists a bit slow... you can get a "loading directory name x of y" type message sometimes. I think this too is an Audi issue as the HD on a PC shows a directory much more quickly.

Otherwise it's good (the above really are minor). The sound is transparent (i.e. the same, as you'd expect as this bitrate in a CAR!) compared to a normal CD and navigating the tree is easy (assuming you use some logic when setting it up). For under £100 (bought new, ignoring cost of AMI etc!) you can have a HUGE archive of music in your car which seems pretty good value compared to other systems I've used (e.g. Phatbox) in the past.

One other thing - I split my drive into two partitions and the stereo defaulted to the first partition on the drive (which has my MP3s, I guessed it would). I can't select partition 1 or 2. I also formatted as FAT32 (I would have to check the manual to see if NTFS/ext3 etc are supported).

Hope this helps someone!

Oaf

Finally had a chance to get out and purchase a 4GB and 8GB USB stick for my A5 sound system. I have a loaded A5 S-line with Navigation and 6-CD changer with NO SD-Card slot. My only option was to buy a $75 USB cable from Audi and place an SD card or USB stick in the glovebox. I'm happy to say that my system recognized both the 4GB and 8GB USB drive so I now have all my 3,554 songs from my computer loaded with tons of room on the USB drive to spare. Subdirectories are recognized as well so I can also sort my music by artist. NO MORE BURING CD's !!!!!!

Hehe ... this is where we find there are different software versions in the stereos, some of which support 4GB (and more?) and others which only support 2GB.


One for the geeks/nerds:
I'm was initially confused by the comments about SDHC as I was previously under the impression that anything over 2GB had to be SDHC so that the memory could be properly addressed. Not the case according to an article on Wikipedia (which in this case does seem trustworthy):

"Compatibility with 2 gigabyte and larger SD cards has been poor, due to the SD/MMC protocol's using a 32-bit address field denominated in bytes. The SDHC standard addresses this limitation by using 32-bit block addresses instead. Both SD and SDHC are traditionally accessed as 512-byte blocks on 512-byte boundaries, so the change to host software or firmware is minor but required. Before SDHC was standardized, various manufacturers "extended" the SD control block fields for their 2 GB and 4 GB cards in different ways. Those cards are incompatible with many SD and some SDHC devices, as they conform to neither standard. All SDHC readers work with standard SD cards."

This is now my conclusion although I should have been more specific and said firmware for the stereo rather than the more general software. Not sure if MMI will display the firmware version for the stereo. Then again I am assuming that the MMI software is different to the firmware in the stereo unit itself but I honestly don't know.

For those who may be confused, think of the PC you're probably reading this on. The CD/DVD drive in your PC has it's own firmware which amongst other things tells it how to read/write to different sorts of disk. This is different to the operating system and drivers found in your PC. Most of you probably patch your OS using Windows update but probably haven't upgraded the firmware on a DVD writer to allow it to recognise the latest 16x or DL media. I'm suggesting the MMI is like the PC operating system and the Concert Stereo is like the CD/DVD drive. Even if the stereo unit does have its own firmware I'm not sure if it's possible to upgrade it.

OK. Basically what the article is saying is that SDHC standardises the way that SD cards over 2GB and the devices that read them should be designed. Prior to that different SD manufacturers had different designs for their cards which made it difficult to ensure that a card reader could handle all types of cards.

So, Wonderstoat is suggesting that the card reader in the A5 is having difficulty reading non-SDHC cards over 2GB but it may be able to read 4GB cards providing the cards use the SDHC protocol. Thing is, when you buy an SD card this sort of information isn't normally readily available.
