Proximity Alerts (too fast to read)

I can't help you with alert timing on screen for that nuvi model but you can add audio alerts using wav files rather than mp3 if that's any help to you:

PS--if you haven't downloaded your Owner's Manual yet, here it is:

The POILoader software from Garmin will ignore .wav files (it gives me a message that says so.)

Also, none of my proximity alerts work now!! Even the Garmin red light camera alerts. !!!!????

Make sure sox.exe is (still) in the same folder as POIloader.

The reason why my custom alerts was not working is that the coordinates I got from Google had the places farther away than the alert. (i.e. School was 300 ft away, my alert was for 200 ft)

I did not have SOX loaded until now. I'll try it and let you know. Thanks

However,
Does using custom POI's turn off the Garmin-installed red light camera alerts? Mine no longer seem to work.

SOX works great. Thanks

...and the alerts are not too fast.
