I cannot get my iPhone and Entune to sync my contacts. When pairing via Bluetooth, I enables "Show Notifications", but there isn't an option on my phone under "TOYOTA Prius" to allow contact syncing. Every time I start my car, the Entune system declared "Contact sync unsuccessful". All of the other Bluetooth features seem to work, I can play audio and make telephone calls. Has anyone has a similar experience with an iPhone? I'm running iOS 9.3 on an iPhone 6S in my new 2016 Prius 4. Update: Alright, so I turned OFF Show Notifications. The next time I started my car, Entune was able to sync my contacts. Problem solved!
By turning off Show Notifications, you may well have limited other capabilities. If you have five minutes, you might want to walk through the step-by-step Setup instructions posted at 'How to successfully connect an iPhone 5S to Entune for all compatible functions' on this site to confirm you've max'd your functionality. Full disclosure, I initiated that thread.
