We are using an iPhone navigation app via Bluetooth. The app will set a destination and give voice commands for turns, hazards, etc. the problem is that when the so begins to talk the Bluetooth seems to be a little slow to activate and mute the radio so the first couple of seconds of the voice from the app are missed. And if the instruction is something like "Turn Left" the entire voice instruction is finished by the time the Bluetooth mutes the radio and starts to accept voice from the iPhone. We also own a 2015 Sedona SXL and when we use the app it mutes the radio then starts the voice instruction. I'm wondering if there is a software or firmware upgrade for the sportage available since the iPhone and iOS software is much newer than the sportage. Any help would be appreciated.
