I've had a Zumo 550 for many years now and last year subscribed for lifetime map updates. I've downloaded the required maps i need but every now and then when I turn the unit on I get a message advising that the City navigator NT 2011 map is out of date and needs updating!!! This after I've updated all the maps. Is there a way of deleting the old version of city navigator off the unit to stop this happening?
Thanks in advance
Chris
