Yes, only a GPS holder and Car Cam.
I never use a phone unless I am the passenger.
I see so many silly dangerous drivers on the phone, including truck drivers and lots of Tradies who should know better.
No, we don't need 1. No one hardly ever rings us anyway, & if my husbands phone does ring, I'll answer it for him. And my husbands knows never to answer his phone, if he does happen to be in the car on his own. Yesterday, while we were out, I saw a guy in his work ute, at the lights looking at his phone! He was on his green P plates, & had to be tooted to move on, when the lights changed to green. Grrr!!!
