Troubleshooting Questions
12.
May I change the warning sounds?
Yes, you
can substitute your own .wav files for any of
the warning sounds found in the
TTWorldNavigator Sounds folder such as
reroute, spdBeep sounds. The SpdBeep sound
is the one you hear when it is time to turn. Do
not change the name of the file, just rename
your .wav file to the same name as the original
file name.

I see a NANDFlash folder in my software path.
Can I use this for storage?

should not be used for any storage. Attempting

GPS device and unplug from the power source.
