Again, thank you both for the reply.
First, akirby I have the same issue using my wife's phone, she has the same iPhone as me.
"The dealer should try reloading the APIM software - not because it needs an update but sometimes it can become corrupted." What is APIM an acronym for?
We both have WAZE installed, I'll mess around with this and see if by turning Waze off if the problem goes away.
Cheers,
