Why can I not make Entune App use my phone via data cable (instead of Bluetooth)

My entune doesn't work unless connected by the cable.

 

I just realized you have a plug-in advance. I just have a Prius 3 so it may be a different system in your car than mine.

 

I have a Prius 4 with JBL audio and nav, and the only way I can connect to the Internet and control Pandora with the audio system is through the cable. I can stream Pandora through Bluetooth, but I have to control it from my phone if I do.

I have an iPhone 4; the dealer told me that Entune doesn't work very well with the iPhone 5.

 

I have the iPhone 5 and I connect via Bluetooth just fine. Pandora works as it should, and I control the music and stations via the nav unit.

PS. I the HDD nav unit, in case that makes a difference.

 

there are 2 system in the Pruis.

1 - Display Audio with Entune
2 - HDD Navi and Entune

system 1: Without a mobile hotspot plan, you must run Entune App on the phone and it has to connect over USB.
with mobile hotspot, you can do it over bluetooth with connecting.

system 2: It works over Bluetooth, however fellow forumers has pointed out one will experience issues when you have iphone connected over USB. The work around many shared here is to run your entune app after connecting over USB.
