Downloading Apps to a GPS

I just read an article on downloading an app to a GPS unit. The app
is PhantomALERT and the URL is:

I am ready to upgrade my Garmin. Where do I go to determine what
Garmin products will support downloading apps?

Thanks.

You don't need any download apps to do that now--works with most any
Garmin and TomTom GPS units that accept POIs. I've been using this
*FREE* service, quite effectively, for the last several years now:

PhantomALERT is a paid subscription service--not worth it IMO.
