Entune software updates

My currrent version is v6673170.

I have a 2012 Prius iv, is there a way to get this upgraded to current version without taking it to the dealer? Also anyone that has had an update done recently what is your version?

Edit:

To clarify I want to make sure I am running the most current Bluetooth revision and whatever controls the usb interface used to connect an iPod or iPhone. I did the Entune update through my phone but it did not update my Bluetooth which is still at 21.202. Do I need to do an official navigation update to be current for everything?
