Dear TomTom your post codes need improvement
Try navigate to :
771 Chester Road
And then compare where you are to the real place (use postcode, or other map service like Google maps) !!!!!!! 6.5 miles away !!!! And that is in the city. So including traffic it could be an hour away !!!!!!
I know numbers are not perfectly ok on your maps but there should be a warning message that you are not gonna get in correct postcode if using this door number ...
Really 5 miles away in the straight line ...
Really really bad
