nuvi 2797 Alerts

I suggest starting with a small POI file that has locations near you and where the coordinates of these locations are within 30 meters of the road on which you will be traveling.

please read
Comparing Alerts - Speed, Along The Road, And TourGuide

What have you tried to load?

When you ran POI Loader in Manual mode, did you check the box for each POI to allow alerts?

Put in campgrounds, rest areas, truck stops, Walmart. Set the alert for Walmart just to test it. Went by two different Walmarts no alert, did check box in poi loader. GPS showed where both Walmarts were as I approached them. Double checked to make sure wav was named the same, exactly the same. Audio set up, boxes all checked on GPS to alert and set to continuous alert. I assume the 2797 is suppose to give alerts.

You may actually be all set. If the Walmart POI location, likely the building itself, is more than 98 feet from the roadway you're on, there will be no alert:

Walmart may not be a good test to see if alerts work because we do not know where the POI was located by the POI file maintainer. It could be anywhere on the property, and if you did not drive directly at the POI within the alert distance, it is proper that no alert happened.

The best test POI would be on a road. When you drive past it you can't miss.

And luckily, Rest Areas Combined was loaded. So a drive by (or simulated route) past some rest areas will be the validation needed.

And if that fails, we'll confirm the sox version and location, wav specs, filenames, etc.

Just to verify you do indeed have alerts set up. Turn your gps on and touch Where To,Custom pois,Walmart then touch any one of the Walmart locations that are set up for alerts. Don't touch go.Touch the i next to routes. Now look at screen and see if you see alert information on left side. If you do, then set up is correct and you can now get to the root of the problem. The problem is most likely that you are out of alert zone (appx 98 ft) if you see the information on the left side. To correct the problem you can then reset the coordinates which would be a large job or go with a TourGuide File set up.

If you have a problem here is a video on voice alerts, Wav and Sox.exe set up https://www.youtube.com/watch?v=dsJTUmvb6_o

Is if the OP entered an alert distance. Just because you check manual, you still need to enter an alert distance for each POI file when loading with POI Loader.
