The map update did not finish normally.

An update on the situation:

I was able to contact another owner of a 370Z Nismo Tech online (his was a 2016 version), and he tells me the 2018 update bricked his Navigation System too. He was told it was a bad hard drive by the dealer, but after comparing notes, it's not seeming like that anymore.

He tried to get his money refunded by Nissan Navigation awhile back, but was given the software "sold as is" cop-out.

However now I'm wondering if the software was never really tested on the Nismo Tech lineup, and it bricks them all (i.e. they assumed it's the same a Coupe but it's really not).

Does anyone know of a SUCCESSFUL upgrade of the Navigation System using the upgrade software on a 370Z Nismo Tech?

Also... I don't think anyone should upgrade using the 2018 software.

Always... going to the dealer on Monday, but I still don't see how they can help. Especially if the extended warranty isn't good or is a type that doesn't cover the Navigation (or the scenario of it broke).
