BMW Melbourne Southbank. Where I bought the car from.
Update - I was trying to get the radio station names on the screen - works on one key and not the other? But they told me I have to come back in March as there will be another update to the software.
I would have thought that upgrades to the software are normally fixing bugs, like windows service packs, so they should be free as part of your warranty.
Did you check with the place you bought it from?
