Install the old version (the one that is around 90MB)
then copy the directories "Drive", "Maps" and "Res" to your PC.

Now uninstall the old version, install the new version.
Then copy te 3 directories from your PC back to your phone

Done!

Edit:
More easy way is just to download the full package that you can find over here

After the download, just replace the old deb file with the new one and you're ready to go!

Edit 2:
Hmm.. Somehow, it does crash for me aswell while trying to run Sygic. (it shows the splashscreen or a second, then it's closing suddenly)
