I found this new version of Garmin for UIQ3:
It is an upgrade from previous 4.10.60. Just copy all the files, EXSEPT system, and then run the MobileXT.exe.
This is Taiwan version, and has chinese and english language. But with the trick of homerjay1977 (http://www.mobinuke.com/showthread.php?t=213350),
you can make it multilingualelete the file "gmsup" in Memory card:\Garmin\Res\Symbian\Apps then you can choose other language than Taiwan, English.. also change keyboard layout - by deleting the file you get multilanguage. Then you have Greek language too.
It is working perfect on my P1i with the latest firmware.
