I am using the android app on my t-mob galaxy to connect to the our 2013 v 3 it seems to work for the most part, my daughter has an I-phone she is going to connect to see if she gets some of the blanked out apps I cannot connect to. I will update here when that happens. We are currently struggling with audio problems front door panels have sound nothing else does.
Just tried it out on the new 13 Pv3 and it works OK. I'm not an Entune guru, but it works as good as the main Toyota App.
