Interrupt offline map download
sometimes it takes days to download a big offline map ... that is not nice, but normal as it is an external restrixiton with those 10000/a day.
BUT: sometimes I need to download something small inbetween but I can not, as there is still that other download pending. From UI it is not clear if an incomplete map will be deleted if the resume is stopped ... or can I restart download later again??? Please make it clear on the screen as nobody wants to loose days of downloaded maps.
