here are all files you need:
http://uploadmirrors.com/download/TT7INLIM/sygic11.2smb.en-gr.rar]anonym.to - free dereferer service[/url]
contain the .sis 11.2 and the folders you have to place in e:\ (sorry it contain the greek map and languages too)
I think it's good idea to delete e:\sygic folder before extract files to avoid unnecessary files in sygic folder after. If you want to save your favourites waypoints you may try to look for files where these information are stored and replace them after (don't know if they work with 11.2 too, i chosed to delete everything).
If you need all language files as I suppose download also this and extract as well the sygic folder and overwrite when asked (some files are in both archives).
I suggest to put the phone in USB mass archive mode when you extract, it's faster and safer, if you can't put the phone in this mode (auto switch to Ovi suite mode) you need to exit from ovi suite and maybe to terminate its process with task manager before connect the usb cable.

now you just need to add maps, use sygic downloader and select ANDROID to obtain the new maps. Once they are downloaded rename all folders from 2013.01 to 2011.09 then copy them in your device, and they will be all recognized.
Russian map can't be recognized, we need to update the license files for it or cr**k the application, any help is appreciated

thank you!
