I updated the maps on my avic5000nex with all new firmware in August and then purchased the Q42019 map update. I did the sync and the navi tool box, but it had an error on the navi toolbox I didn't realize until doing the update on the deck. It shows it has maps from 2013 and 2019, but it clearly did not upload the 2019 map update. When I use the Navitool box tool it only shows the 2013 maps as the only available maps I can download to the usb.
I tried factory reset but it doesn't erase the maps database which is now showing almost 4gb of space being used.
