I have a contact who is in electronics purchasing manager high up in a national (USA) outdoor equipment retail store.
He asked me not to name the store, so I won't.
He told me that their stores plan to phase out selling retail GPS units over the next several years, because smart phones have become so capable and are superior in terms of map quality, screen resolution, and low cost.
So, if you have any stock in Garmin, and that would be a good time to get rid of it.
