there is a fix for that...just search for sygic mod or sygic problems thread, and there is a solution for that...after you change the settings (i think it was something like positionfilter - false, antialising - false, and one other value to 0) the maps works perfectly, and also is very accurate!

Just read one of them threads, and you'll know exactly what to change...the above settings are from top of my head, hence its you should find the correct settings.

Good Luck!
