I have a Garmin 3790t.
WAV file did not work.
MP3 was no problem.
Although this is a new experience for me, I doubt that it was a finger problem.
As mp3 worked I did not look any further for solutions.
Hi All,
I have a Nuvi 760 and have only ever used MP3 with no probs. I would have thought that WAV format would use to much space on unit or card.
Sound quality through car stereo is pretty good.
Cheers.
Ok I had a 760 and the mp3 worked fine with imported poi using a csv file bmp file and a mp3 file
I now have a 1490 and did what I did previously to load the POI using mp3 file. The sound did not transfer and all I received was a Garmin "DING" when the alert was on
Did a bit of research and found I required a wav file so downloaded the wav file instead of a mp3 file. The POI loader than told me it couldn't load the wav file.
More research and found you required a sox.exe file loaded in the POI loader start directory as outlined in (and they tell you where the sox.exe file can be found)
As you all know, when sound is recorded, it is represented electronicly as WAVES. So, In order to store this sound on your computer, the waves must converted to digital format.
It is known that .wav format files gives out more frequent sampling will give a more accurate representation of the wave. In fact CD quality sampling is done 44,100 times per second. Each one of those 'samples' is 2 bytes in size (16 bits).
However, MP3 was developed as a form of compression which reduce the size of .wav files, with MINIMAL loss of quality.
MP3, also known as MPEG layer 3, has become a popular format for reducing the size of audio files. Most of the music available for download is found in this format.
Conclusion, if you have enough space, go for .wav format, if you have insufficient memory space, you should go for .mp3 format =)
If anyone has a question, the Garmin 1490 does use WAV files. As you probably know, sox.exe has to be placed in the same directory as POI loader. Works great! You will then get a new menu option to enable/disable the audio alert.
