Ok - here goes...
1) Download the .zip file
HERE(You can do this directly to the phone, if that is easier, or use a PC cand connect the phone to the PC via a USB cable...)
2) Unzip the file, which will then give you 14 individual files - 7 ending in .itn, and 7 ending in .itf - it is the 7 .itf file you are interested in.
3) Move the 7 .itf files to the 'itinerary' folder within the Sygic program on the phone.
(You do this using the 'My Files' App, by selecting them, and 'Moving' or 'Copying' them to the new location)
The new location is something like 'Android - data - com.sygic.aura - files - Res - itinerary'
Does that help?
