I've bought GPS from Ebay. On GPS's SD card installed PolNav navigation system. Everything works fine, BUT don't save My POI, favorites and etc. Maybe anybody knows why? How I can solve this problem?
PS: Has anybody tryed to change navigation system on this device?

Did you install the new GPS software directly to GPS or to a memory card?
