I contacted Kia Motors. First I got, contact your phone provider...I pushed back. They than instructed me to call the dealer; my pishback, Kia is the expert if there is a way to chnage the Phone audio, it can only come from Kia. Cannot be my phone causing Incoming calls to play a Musical Tune. They than contacted the Kia Audio unit...who said to download Zedge and select a ringer, that would change the Niro's ring. I told them, not so. I have Zedge and my phone ringer is a Zedge selected ring tone.
I truly believe the Musical alert of an incoming Call thru the Kia Sound system is dangerous. As I wrote, the 1st time I got a call and heard the Music I immediately thought something went wrong with the Radio and it changed channels. Even the 2nd time, days later, when I got another call it confused me a little... I conveyed this to the Kia Agent who said that they would request a call back from an agent in the Audio unit within 3 to 5 days. I hope that call is placed.
