In a bit of trouble with my MMI. Recently tried to update it to version 5570 from 2120 and CD1 worked fine, then CD2 had an error which has screwed things up for me. It opens and loads 'Handyvorb2' but when it gets to 99% it comes back with an error. 'Error 152 from device'. Searched around every forum on this but couldn't find the exact cause. Any ideas? Do I need to downgrade the software for this? Worst still, contacted my local dealer and they don't do the updates so it seems I may be on my own with this one. Called Audi Uk and they said they would look into it and get back to me. Who know's? Any help would be appreciated.
