I have not been able to get the new infotainment system to show my Text messages from my phone, Moto X 2014. I also tried an iPhone, Nexus 5, and Samsung Galaxy S5. All pair just fine, but no envelop icon.
Many features will not work through mere bluetooth connection you have to plug it in to the USB connection on the 2015. You may try that to see if it works through hard connection at least.
No luck. Thanks for the suggestion TheJ. My car doesn't recognize any phone plugged into the USB port. It's weird and my local dealership has no idea why.
Got my '16 WRX Limited to display and read texts, (displays text only when stopped). Very cool. Running a iPhone 6. I believe it works with bluetooth or USB for me. I wish I could voice recognition replies vs. the short list of replies to choose from. I did two thing that made it work ( because it didnt at first)
1.) I turned on "show notifications" in my phone bluetooth menu under the "Subaru" connection.
2.) I downloaded the Starlink app and installed it. ( I believe this is what got it to work)
