I have two PS3s and I back up/sync my game saves via USB. It never occurred to me that the 2nd PS3 (acquired only about two months ago) might be default to KPH and not MPH. The 1st is kept in the salon for guest/family use whilst the 2nd is solely for myself in my bedroom. A mate had a go in one of my other cars and apparently swapped it over to MPH after he noticed. He was kind enough to show me where he changed it so now the 2nd PS3 is also MPH.
Had a good laugh he did. 🤬 Thanks any for responding you guys.
