thanks bjjfc for ur reply.
ive follow all step that u mentioned there. ive no problem before and have succes in all installation on brand x gps device.
this is my first time i face this problem on this WayWay gps device. ive trying to install garmin, igo, sygic and all is working soo good.
this device using com7 4800braud (knowing from garmin & sygic gps satelite info).
did i brick the oem papago software by doing cut&paste/backup before? and this WayWay device has blocked me to execute papago? i mean this device only running successfull by installing papago using oem exe file / oem cd's or something?
thanks to all...and sorry for my english..
