UPDATE:
Please delete this post, through a stroke of luck, I was able to see a couple extra menu commands through a UTube video I did not notice.
Also, the unit would not see (or allow) the SD card I had (I tried 3 of them!) I finally tried with a USB stick and I was able to get the unit activated.
WOW What a pain... one would think it would be an easier process.
Thanks!

Okay, I've been fighting with this half the night now.
I've google and searched, and came up empty handed.
I just purchased a AVIC-7200-NEX tonight and got it installed in the car.
Discovered the maps are 2 years old, so I started looking into getting them updated.
Found the maps are provide by HERE, and you need the APP: Naviextras Toolbox to update...
But through the toolbox, I can not connect, I can not log in, I can't view any maps, I can't do anything!
I tried to install AVICSYNC on my Android table, but its not compatible (Samsung Galaxy Tab S2 - not a phone)
It installed on My Ipad Mini 4 (No cellular) but wont connect through CARPLAY.
(although it connects and plays all my audio and video - and sounds AMAZING)
So now I'm at a loss. There has to be a way to update the maps without cell phone?
I tried to plug in a SD card, but I see no way of getting the required info to save from the stereo to activate it with the toolbox software.
Help?
I'm I SOL without a cell phone?
