I have just purchased a 6250 (19/09/2020) for London navigation due to topping up over £300 in fines for new bus lane routes, cycle routes, no left or right turns etc.... my original 5 year old tomtom just wasn't able to deal with the changing traffic routes in london.
To my dismay the new 6250 (updated 20/09/2020 over 9gb) got the 20mph speed restrictions wrong displaying the road as a 30mph, these are old changes, tried to take me down bus routes (one for which I was fined) and tried to direct me through newly established cycle routes.
Am I naive to think a brand new top of the range satnav should be able to route me through London without increasing my tally of fines in this already impossible maze?
