I do not see where you are coming from with such a statement.
I vastly prefer my Garmin 760LMT unit to the in dash GPS in my greyhawk.
Firstly, upgrades to software and maps are FREE for the life of the unit. Updates to most in dash units must be bought. To the tune of approx 80 to 100 dollars.
My Garmin brings an additional layer of functionality that the in dash unit does not. I can search for local grocery stores, campgrounds, restaurants, etc.
It also alerts me to traffic and road conditions when linked via blue tooth to my cell phone. A HUGE help when there is an accident ahead. It will suggest alternate routes.
It also alerts me to road conditions not suitable for my RV, i.e. bridge heights, sharp curves, etc.
And when the sun is shining on it I can move it so I can see the screen!
Very happy with my Garmin and will replace it when it quits.
