I currently have an Audi A4 2009 and the Radio is Version 0211.

I want to upgrade it to the latest software so it fixes the Radio Reception Issue and adds SDHC compatibility.

The dealership told me since there is no error code they can not upgrade the radio with out charging me.

Can I put that code ?

Upgraiding the software inside Audi Concert Radio | Audi Forum

According to here:

UltimateVW.COM | Keskustelu

The SVM code for Audi maintenance shop upgrade to Radio Concert (Symphony too maybe?) upgrade to 0310 SW and SDHC compatibility is:

SVM: B856A001

The upgrade is titled to fix some radio reception, but apparently SDHC compatibility comes as a bonus.

Just give that code to your workshop and hope for the best.

 

Did it work for you? I also would like to be able to play SDHC cards.

 

Even better I would like to be able to play an iPod. See lots of aftermarket adapters that "should" work but not sure if they really do and also be able to control it all through the radio.

 

It's funny you should ask. I brought it in to the dealer today.
I already have an Ipod adapter but it in the glove compartment. No point having an Ipod and an Iphone so my Iphone goes in there.
