There was a previous thread about problems downloading the free map updates on the W213; most people seemed to get stuck at around 66% completed. The solution was to go to Mercedes Me, and download the updates onto an SD card. This worked for me last time. I've just noticed on Mercedes Me that there are more updates available, so I started the manual download process. The site then told me my version of download manager needed to be updated, and that to do that, I needed the latest version of Adobe Air. The latest version of Adobe Air is chargeable. So it seems that for my free updates I have a choice between a free in car system which doesn't work, or an online download system which isn't free!
