It all comes down to where you are buying a new Garmin or a second hand one.
Do you homework as to what you are looking for in a GPS Unit.

Garmin is only trying to protect what they have so users can not come in the back door to get something for nothing.

I have a lot of money tied up in Garmin products and they all work. If I need a map that did not come with what I bought because I am planning to say spend a couple of weeks in the US and I have an EU Garmin.
Then I buy a one time map for the US the chances of going back would be very small.
Now here is the EU there are 2 types of GPS unit setup.
You can get the class classification:

Newer Garmin GPS's

LMT-S <----Needs access to smartphone for traffic
LMT-D <--- Has Dab+ built in to get traffic

I have 2 units with LMT-D that came with life time Speed Cameras.

As for LMT-S that need a smartphone I avoid them.

So always do you homework when thing about a Garmin Unit and if it really fits you needs and not have to patch it to get what you want.
With the newer Garmin that is not working any more and I do not see anyone trying to take on this new format that Garmin has.
