Hi guys. recently purchased the above unit. When connected to MY Drive and under my content, maps, there is no map. in place there is an advert to upgrade my device . The map installed is United Kingdom and Republic of Ireland 1011.9039. I understand there is an update for this map but not showing on My Drive. Shown is a map share community map update but when ticked am unable to download the small item. Any thoughts would be appreciated. Thanks in advance.
