PiP: All the software versions...

I am not sure of the specifics, but the software versions are different between the Advanced and the Base, so when talking about this, one has to be specific which model one is talking about.

 

Grace Note (AT): 05052 (2012-06-1)
. - (found clicking update under general tab in setup)

I assume "Grace Notes" is already installed. I had it with a Pioneer radio in another car and it provided CD track titles without problems. I was surprised my 2011 Lexus IS and my 2012 Prius Plug-In Advance won't display CD song titles. Am I missing something?

 

So I go out to the wife's PiP Advanced to check on EnTunes version running on the Nav and press Info, then Apps and it tells me there is an update available. Do I want to update Yes or No? So I say Yes and under 60 seconds I can verify that EnTunes on the Nav system is now running 1.2.230393.
I think the over the air (OTA) update was via the cellphone SOS part of the Advanced Tech. Pkg. I didn't see any data transmitted over my personal cellphone running Entune after the update.

So it looks like sometime between July 8 (OP) and Nov 24 2013 Toyota updated EnTune for the PiP Advanced.
