I'm wondering where the app gets information from to display the current speed limit. I have a local road that has a 30mph limit but the app shows 25mph. It used to be 25mph but was increased to 30mph years ago.
As they are using Garmin/HERE maps it will come from them.
Regrettably all the mapping companies have errors that never seem to get dealt with....
The road outside my house is 30MPH and has been for decades. BMW says it's 60MPH!
