Hi,
If we haven't yet welcomed you to the Map Quality Forum then please feel at home here.
The issue of inaccurate Post Codes in our UK maps is known and has been reported but it will do no harm to pin this particular zone you mention, in Map Share Reporter (as has been advised) - more especially because of your research.
Lars' advice applies to all places one visits - even the one-offs because you never know ..... - take a poi "at the gate" as it were, give it a recognisable name and store that in Favourites. Remember then to backup your Nav Device regularly since you will hold valuable information then. If you do this by rote, you'll have a destination name to route to and a search in the map becomes superfluous. I do this and have done so for years. I have some 25 000 "own poi" taken in my travels - clearly I keep only the regular visited ones in unit and the rest stored off device in the computer and its regular backups. Selection is thus much quicker and is secure.
Am a little concerned at your inability to make an MSR contribution because I do think this is important for all of us. MSR will most usually open at or about your last location and if the zone in the map you need is off view then use the search feature (top right corner):
The 'Find Location' field will shift the map to your search string and then you can use the zoom function to get in close enough to specify "there be bad Post Coding in this zone". The MSR map can be shifted by clicking on it and dragging. I'm still quite new at it also and find I need a few clicks and zooms to be able to plant that pin
Choose a Field for your report (in this case use Other)
Once chosen, you'll see the pin. Drag it to the location you want and drop.
Job done! Hope this helps
