This section of the A1 to Baldock services further south shows as "E15" on my downloaded map on my Garmin. I have realised that it is part of an international route but feel it would be helpful to see it come up as "A1" Can you help? 

I have also found a way to use the postcode feature on my Garmin with the open source map you kindly supply. I use the outdated map to do a postcode search and then switch to the open source map and extract my postcode search from "Favourites" and it works! Keep u the good work and Thank you!
