I have successfully installed
Sygic Mobile GPS complete with maps and voices.

Fully operational and tested against dedicated TomTom 730 in UK, works flawlessly, no issues whatsoever.
Before first run, start and minimize GPS data from Tools menu due to GPS hardware detection, later it's not necessary, it will switch on your GPS module automatically.
Peace!
PS: I'm still waiting what it's gonna be with Garmin Mobile XT... any news? anybody?
