I need your help pls. I installed the latest map update (Full Coverage of Australia & New Zealand 2015.20) for my Nuvi 3760 - gave me a notice that update was completed. When I disconnected and turned on my Nuvi Navigation system, it remained on the garmin start up screen and stayed like so for 2 hrs. now. It is not even recognised by garmin express nor my garmin dashboard.Pls. help
Optional Information:
What have you tried so far?: I have tried to switch it on and off so many times but still failed.
