I often receive Mazda Navigation Update emails from mazda@notification-naviextras.com. Is this a legit Mazda address?

They want me to download the Mazda Toolbox.
I have sent them multiple emails asking how much the update is but I never receive a reply.
I see Map updates on Amazon but don't know if those are legit and/or worth the price.
I generally use my phone for GPS via CarPlay.

 

E mail is from one of Mazda's 3 satnav suppliers, so is legit; when you d/load the legit MAZDA TOOLBOX, then
insert SD into your PC to proceed.

MAZDA TOOLBOX UPDATE must be used for recent cars using Generation 7 nav equipment.
