I think that my TomTom is showing the speed limit on the road signs in kmp instead of mph , anyway it's incorrect and does not match the road signs. Is there a way change it in settings, although I'd thought it should be picking up the right speed limit in miles from the default setting ( UK)?

Thank you in advance
