Ideally the navigator 2 software is installed on the internal memory and the maps to internal/external memory. Many customers are having problems with 'some' SD cards made in China but not SD cards made in Japan (freezing). What you can try first is to flash format your SD card to FAT 32 (warning: this erases all SD card data) and then reload the maps to it and see if the same problem exists. If the same problem exists then delete the maps and load a very small map to internal memory of the PDA only. If this works then your flash card is suspect. A 3rd party unsupported website for a flash format utility is located here:

ill see if this makes it better
