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
