does anyone know if there's a website for informing sat nav mapping companies of errors in their maps?

all sat nav systems send visitors to our house down completely the wrong road to the rear of our property that has no access i'd like to inform the mapping companies of the error so that it's corrected in the future. if everyone that knows of mistakes does this, then the mapping will improve

i have seen tomtom ads where they say users can use map share to change maps on their device that can be shared with others using their own software, but i can't find anywhere on t'internet to do it simply online

 

i'm not sure how mapshare would actually work, ithout actually drawing in the road you are driving dow with yur finger and then uploading it

Try that, they do the mapping for most of the sat navs about now

EDIT: done
