So recently I bought a Samsung Exhibit II. It has a different file partition management from my LG phone. Exhibit II claims to have 4GB of internal ROM, but 1GB is reserved for OS, 1GB is for internal ROM, and another 2GB is for internal SDCard. The internal SD card is located in /mnt/sdcard/, which is actually the external SD card on my LG phone. And the real SD card is located in /mnt/sdcard/external_sd/. Now for Navigon, it always download maps to /mnt/sdcard, since the partition is only 2GB, it’s gonna be problem if you want to download lots of maps. So you have to change the default folder to /mnt/sdcard/external_sd/. To do this, you need Root Explorer, and the following copied from HERE:
you have to save the [/mnt]/sdcard/Navigon folder to a safe location. then just put it back to your internal sd card after a fw flash. (also external is possible, but you have to edit /data/data/com.navigon.navigator_checkout_eu40/files/NaviKernelConf.ini [i have eu version]
from
DataPath = /mnt/sdcard/Navigon/data/
ExtensionPath = /mnt/sdcard/Navigon/poi/
MapPath = /mnt/sdcard/Navigon/map/
SoundPath = /mnt/sdcard/Navigon/sound/
to
DataPath = /mnt/sdcard/external_sd/Navigon/data/
ExtensionPath = /mnt/sdcard/external_sd/Navigon/poi/
MapPath = /mnt/sdcard/external_sd/Navigon/map/
SoundPath = /mnt/sdcard/external_sd/Navigon/sound/
so you can have your maps also on the external sd)
