Aera 500, aera 510, aera 550, or aera 560 screen says USB on Wrong Port

In order to perform a database and/or software update, it is necessary to connect the aera® 5XX avionics navigator to the computer via the USB-mini-USB cable provided in the box. The mini-USB portion of this cable plugs into the aera by removing both the mounting bracket and battery door. The battery door is located on the back of the aera, and can be removed by sliding the button on the bottom of the GPS until the battery door lifts open. Behind the battery door, there will be a mini-USB port located just above the battery.

This is the correct USB port which you need to plug your USB cable into in order to perform software and database updates for your aera.
