iPhone 7 and Alpine radio Bluetooth connection

[ProjectDirector]

For the last few days I have been trying to connect my new iPhone 7 to the Alpine receiver and no luck.
Looked all over Internet and had fixes on phone but none works.
Anyone out there that may have had a fix for this will be greatly appreciated.
Btw the 110 is 2013 model.

Cheers

Problem resolved
For everyone's information the alpine radio holds 3 devices in the Bluetooth memory so mine was full from my kids devices. All I needed to do was to delete one device
