2015 Prius 2 aftermarket GPS &etc

So the wifey is hot on getting a Prius, and we're kinda torn between the 2 versus 3, but I read plenty of negative stuff about the navigation and entune that spending an extra 1100$ doesn't seem to make sense....

(I'm looking at local sales prices around San Fran of 19300 versus 20400 for the 2 v 3)

Anyway I'm having a fairly difficult time finding a good built in unit with GPS and apps and etc to fit into the Prius 2.

Edit - (Well I just found out I can't insert links, so maybe someone can add them in reply when they find the items ? You can just insert the item number into the AMZN or Ebay search box... thanks)

This is the closest thing I found, but it says it's only for 2009-2013:

Amazon item # B00OLM8EJC --
Pumpkin 8 inch Android 4.4 Kitkat For Toyota Prius 2009-2013

(Although this Pumpkin one only has one review the other Pumpkin ones have lots of decent reviews.)

And this one looks similiar but has contradicting info where is says upto 2014 and then yes to 2015:

Ebay item # 191611200883 --
FOR TOYOTA Prius Car DVD Player GPS Navigation In-dash Stereo Radio System BT

I realize the sellers are in China, and info not always most reliable coming from them...

I talked to a couple of car alarm/stereo shops today and neither of them had a unit that would work for me???

I read some threads where peeps did their own custom tablets, but that is not me, so I'm not really sure which gps/radio/apps/etc would be good for a 2015 Prius 2 ???

I'd be happy to spend the money on the P3 if the nav/entune system was decent, but by all accounts it isn't very good.

(And we're not interested in a solar/moonroof, so no reason to get a P3 for that.)

I've searched high and low and so far I've got nothing that I can tell the wifey for 100% certainty that it will work for the 2015 Prius.

Any links or good words about a specific head unit for a 2015 Prius 2 would be appreciated. Thanks !
