audio set-up for beginners [continued]

[TheUninvited]

To those who are using Pioneer 2 din head units, & have an iphone 7/7+, did you encounter any problem? I installed a pioneer 2850 in my wife's Innova. Her previous phone was an iphone 6+, & we had no problems making waze show up in the head unit, but when she got the 7+, only black screen shows in the head unit, but audio can be heard.

Try ko later sir. I have a 7+ and Pioneer 5850.
