Please help me out guys, i'm trying to upload POI with icon and red ligh camera into my new Garmin 3790T but no luck, i'm using Garmin POI Loader to transfer to GPS still no luck.
I to do the same process to Garmin 1490T (SD Card) and it's work well but not the Garmin 3790T?
Just thought it would be worth a quick check to see if this is a problem..
Connect your Nuvi to your PC as you would normally to load POI.
Wait for the box that comes up and click on 'open this folder' (may not be exact).
This will open Windows Explorer with the Nuvi drive showing what folder and files are on the device.
You need to open 'computer' or 'my computer' (I'm using Windows 7, so may not look the same as yours).
When you click on 'computer' you will see all the drives connected to your PC including your Nuvi and any memory cards or slots.
It should also give you an overview of the size of the drives and the space left on them.
(If you cant find 'computer' this way, close the window, go to start button and click on 'my computer' will get you to the same place)
The only purpose of doing this is to eliminate lack of space as an issue.
If it proves to be an issue, then we need to look at cleaning up your Nuvi, or adding a memory card.
If you haven't got many POI loaded yet, try using POI Loader to remove all your exisitng ones on the device.
Then reload all the ones you want, seems sometimes that it wont overwrite old POI successfully - no idea why?
Also, check that you have the latest upgrades and the latest POI Loader.
I was able to get my POI folder to load and display on the 3790T by doing a Garmin master reset:
1. Start with the unit turned OFF and unplugged from power
2. Power ON the device
3. When the copyright screen appears press and hold the lower right hand corner of the touchscreen
4. Remove your finger from the touchscreen when a message appears that says Erase all user data?
5. Touch YES
6. After resetting go back to POI Loader and reinstall POIs. After restarting the Nüvi the POIs should appear appear.
P.S. Do not forget to backup your favorites before proceding with the master reset.
You need the BMP file for the icon and the WAV (or maybe the MP3 - depending on the model).
Download from the same place you get the POI.
To use the WAV files you will also need SOX.EXE, (found HERE) and you will get the directions as to where to find it and how to use it.
