Steps to reproduce:
1) Open 'Where To?'
2) Choose 'All POIs'
3) Choose menu (three lines)
4) Choose 'Spell Search'
5) Enter something to search
6) Choose an item (It does not matter which one)
7) Press 'Go'
8) Open 'Where To?' again
9) Choose 'Set Via Point'
10) Choose 'Use Map'
11) Choose some street on the map (It does not mapper which one)
12) Instead of adding the via point, you now get the message 'Only 50 points can be used for On Road navigation'
Maybe Garmin starts me paying as a beta tester *sigh*...
