3790 custom POI mp3 to wav file problem

 

Recenlty uploaded to my 3790 red light and speed cameras custom POI files. Using the instructions provided from the path www.poi-factory.com/node/25730. I was able to upload successfully the csv and bmp file but the wav file will not upload. I know what the problem is but not sure how to fix it. I used one of the provided alert messages from this website and used the audacity program to convert it from a mp3 to a wave file. The problem is i changed per the instructions the file to be PCM, 44,100khz, 16 bit mono wav file then exported the file to the folder for uploading. When reloading the file using audacity program I noticed the file still says 32 bit float even though I changed it. How do I get the audacity file to retain the changed settings correctly for me to upload to my 3790?

Audacity

Right click on the wav file and click on properties. You will probably see that the wav file is 16 bit.

Audacity is just showing a default bit rate when you re-open the wav file. That would not make it 32 bit unless you exported it again while set at 32.

Anyway sox would handle the 32 bit with no sweat and would convert it to standard Garmin format. (That is why POILoader calls up sox when there is a wav file present.) So I think your problem is elsewhere.

The usual suspects are double file name extensions and/or names not matching the other two files (excepting extensions).

To check

In case it is not clear (or known), I will add that the place that the 16 bit is set for an exported wav is in the Uncompressed Export Format Box on the Edit - Preferences - File Formats Tab. The original default selection in that box is "WAV (Microsoft 16 Bit PCM)" and that would be ok to use.

No matter what is shown on the screen where you first open a sound file, the above will control the specs of the exported wav file.

Just as I suspected 3790 accepts mp3 files

On a hunch i tried to use an mp3 format instead of a wav file for the red light and speed camera alert files because i couldnt get the wav files to transfer. The mp3 file went through no problem. FYI the 3790 also states that my cell phone does not work with my unit but i tried it anyway and not only does it work it also transfered my entire contact list. So i guess you just dont know until you try

IMHO

IMHO, you may have got the mp3 file to transfer(?) but you will not hear any "alert messages" as the 3790 has no support for MP3.

There is nothing to stop POIloader from creating a poi.gpi file for the 3790 that includes the gpx/csv, bmp and mp3 files for the red light and speed cameras. Since the 3790 has no MP3 support you may see the camera popup icon appear on the map screen as you approach one of them but I would me more than a little surprised if you ever hear an "alert message" for any of those popups.

Go to https://buy.garmin.com/shop/shop.do?cID=134

Pick your unit and at least one other unit. Then scroll to the bottom of the page and click the "Compare" button on the lower right.

In the resulting comparison, look to see that you have bluetooth so it was always possible your phone should have synced. I assume that you went to the Garmin website and your particular phone was not listed. Is it a brand new model that might not have made the listing yet?

Look further to see that you do not have a mp3 player.

So back to the .wav transfer. Tell us how you were trying to "transfer" the file. Remember it has to be in the same folder with the POI file for which it will be used and has to have the same name EXCEPT FOR THE EXTENSION (so make sure your PC shows extensions)

let us know the results.

Im lost

Ive done everything correctly the poi show up on my map when i drive by them and the little grey text box shows up saying what it is supposed to say but cant get the dammn thing to do they alert message. Im following all the directions correctly and the poi loader gives me a message couldnt transfer file becauses it does not support the format it is in (wav). The files are all named correctly with correct extensions and the sox file is in the same folder with the wav file as instructed. I even tested that website where u type in what you want it to say and creates a wav file and that wav file wont transfer with the poi loader it gives me the same error message "Could not transfer file wrong format"
HELP!

can someone post the wav file with any appropriate alert

Please post a wav file guaranteed to work with an appropriate alert that somebody is already using on their garmin 3790 It would be greatly appreciated because no matter what i do i cant get a wav file to transfer via poi loader program constant error message is unable to convert wav audio file so did not transfer

Got it to work

i put the sox file in the poi loader folder and the individual poi folders and it trasnfered the files over with no errors and the sox file prompted me each time it moved the wav file. Gonna run some test routes but i think i got it

Just in case

Just in case this doesn't work out, I make sure that sox.exe is in the directory with poiloader.exe and have my csv, gpx, wav, and bmp files in my POI directory.

What's odd to me is that I never have sox prompt me to do anything. PoiLoader silently uses sox.exe and creates the file on my nuvi.

Does anyone else get sox prompts like spotty when using POILoader with wav files?

Personally

Personally I'd never know it was on my PC unless I went and looked for it. Like you I've never seen it pop up or prompt me for anything.

tested and it works

tested all my routes and alert messages they all work now. I think i have downloaded about 20 POI files today and they all work. Thanks for the help!
As far as the sox if I have a alert message in the poi folder it comes up and asks to run during the transfer. I probally could disable the pop up but no big deal

That's great

Great news. I only offered the pop up message as an issue if things failed and we had to look further.

I wonder if the permission thing is a Windows UAC issue rather than a POILoader or sox issue.
