SDHC Cards working!

**nickhx** · 21-07-2009,05:09 PM

Some good news folks...

My Audi A4 B8 went in to the garage this afternoon for a software update to correct a problem with the traffic information programme on the concert radio (MMI low) (the radio was not remembering the volume I had set for the traffic information updates).

As a result, my hardware / software combo which was H11 and SW0130, has now been upgraded to H11 and SW0310.

More importantly, I have just checked and my 8GB Transcend SDHC card is now finally working fine in the radio!!!

My car is one of the first production models (built in September 07) so clearly this upgrade does not need new Concert Radio hardware.

Some follow-up research on the internet this afternoon suggests that the SDHC functionality was introduced as from Software version 0310, so you may wish to check your own versions of the MMI and see whether you can get your dealer to do the update.

I will be ordering a 32GB SDHC card shortly and will post back the results.

Cheers

There's been a lot of reports of the cards working but the question is can you access everything on the card.

e.g. if you load the card up, can you access all the tracks as previously people have found they can only access the first couple of Gigs worth.

Loaded up my 8Gb SDHC card this evening with about 5 gig of files (about 700 files) and all seemed to be working ok, with no files obviously missing.

From reading around it seems that 4,000 files is the new limit. Haven't been able to test this yet, but sounds like more than enough for my usage.

You might be able to see them all but when you try and play some of them the track name could turn grey and say that the file is corrupt (even though it's fine when you play direct off the card on a PC). Have you tried a large number of the tracks on your card?

What I've noticed is that if I remove some of the working tracks suddenly some of the previously "corrupt" track start working. So as said above it doesn't seem as if it's a size of card compatability issue in terms of reading it but rather it will only play up to a certain volume of files.

Actually scrap that, I've just realised that the tracks don't work are nearly all mp4s rather than mp3s. Very odd especially as some work but others don't. I'll try converting them to mp3 and will let you know how I get on.

You could also try formatting the card with Panasonic's special SD card formatter program (assuming you have got Windows) which you can google for.

I have read elsewhere that this can solve the problem of missing files (apparently Windows own formatting is not 100% compliant with the SD card format!)

Any idea on how they were able to upgrade the firmware of the head unit? where do they connect, software they use? etc? I have spoken to Audi NA and they insist that it is impossible to upgrade the firmware...

AFAIK, only the dealer can perform the update to the Concert Radio Software if it is MMI low via the head unit.

However, if you specifically ask for the software update to enable SDHC, nothing will be available as Audi do not consider it to be an "issue", as the original specification for the A4 Concert was only to read up to 2GB cards.

So, the only way to get the upgrade is to ask your dealer to repair the issue with the traffic volume (see my first post above) which should be done under warranty. That fix involves updating your MMI software to version 0310, which also as a helpful by-product, enables your Concert radio for SDHC!

Doesn't affect me, but that is the kind of collaboration that really makes me appreciate forums

A fantastic tip.
