My screen mount on my Tomtom go live 940 is broken. The little ball is perished and so the map is no longer supported for me to be able to see it.
I have tried buying a replacement online but the one I got did not fit. It was described as being compatible but the little ball connection was too big.
my device is about 10 years old.
can anyone help me get a new one.
