How to find a feature phone with phonebook sync (ideally with Google Contacts)?

Question

Mobile devices

To help an elderly person, I am looking for a push-button telephone (due to poor eyesight) with a good phone book with the ability to synchronize (ideally with Google Contacts). Synchronization is required, since the person is quite sociable, at least once a week he receives the numbers of new acquaintances and it will be difficult to manually transfer the notebook from csv to something human-readable and back.

Answer 1

The current push-button phones are all terrible. I'm looking for one for my parents.
Not as a solution, but as a direction to look for - try googling about syncing Symbian S60 with google contacts. It seems to be working before, as it is now, I don't know.
You can find a normal S60 button on the secondary.
