Hello everyone,
Does anyone know where I can find what firmware version my 2009 S5 (US Spec) shipped with from the factory?

I brought my US spec car to Germany, tried to update MMI so that Nav would work here, but no luck. It just made things worse by removing menu options and disabling the backup camera. I want to go back to my original firmware, but I was foolish and didn't write down what I started with!

Thanks for any help!
