They have discontinued some of their GPS units but they are offering very good discounts for existing Garmin users who buy new products. (They will sell the product as a "replacement" product; as part of this, they will no longer provide updates for your existing device.)
You can chat with a rep on the Garmin site; they might have an upgrade that would suffice.
That would be a last resort. I don’t need a newer GPS unit. I need a way to download GPS data that is already being tracked through my phone.
