I am using Hyundai Exter manufactured in Jan 2024. I was using iphone 15 & was able to make calls without any trouble. I have purchased iphone 17 on 26th Oct 25 & updated software. When I am making phone calls voice on other end is hardly heard. Tried difference phones including other phones, it works fine on same car. Used my iphone 17 on other cars and it works good. I do not know what might be the problem.
iPhone 17, iOS 26
While in your car and on a phone call, adjust the volume using the volume control on your steering wheel as opposed to the volume control on your iPhone.
I would unpair your iPhone 15 from your Hyundai, make sure your volume is up on new phone and try again. Also double check your Apple CarPlay is working too! I had my phone unpair with my Hyundai Santa Cruz 2024 on a trip while I was using maps! What a nightmare! Good luck!
Try to check with the same other Exter car...
