Must be older unit.
Buddy of mine has 2015 model.
He had to order a new Bluetooth chip for his.
He installed it himself and believe me, if he did it, anybody can. Lol
My 2021 Ultrex moves 2-3 ft at most with 20mph wind.
I think it cost him around 300 bucks and he already had a Bluetooth puck.
That will cost extra if your friend doesn’t have one.
