I was doing a little planning for a trip to Antwerp in Belgium

[biggles]

I live in northern England. I entered details into the BMW app and it advised me that i needed to download more maps - fair enough, they take up a lot of space in my phone. So, it tells me to download maps for Southern England, Belgium, he Netherlands. All this is fine. But for some weird reason it also instructs me to download a map of Northern Ireland! Why?
