Let us back up even further - tell us what model you have.
("3rd generation" is a marketing term.)
Use the first few characters of the device's serial number and this chart:

As pointed out above by GM, some models shipped with more than a single model display during their production run.
And some models shipped with a "diagnostics mode" that you can not exit except by using a serial port connection.
