Hyundai Tucson CarLink/OnCar Connection Error

I own a 2017 model Hyundai Tucson and I have never been able to use the CarLink feature in the vehicle’s multimedia system. Since the day I bought the car, every time I try to connect, I constantly receive the error message “Please turn on the GPS navigator” even though the GPS is turned on and the system can see Wi‑Fi networks. At the connection stage, the system either freezes or gives an error and terminates the process. As a result of my research, I found out that this system works through an application called OnCar. However, this application is no longer supported on current smartphones, is not available in app stores, or even if installed, does not work properly with the latest Android/iOS versions. In practice, the multimedia screen in my 2017 model vehicle serves only as a radio, while navigation and smartphone integration are completely unusable. The main problems I am experiencing are that the multimedia system is dependent on an outdated and abandoned software (OnCar), that it constantly triggers a GPS error which blocks the phone mirroring feature, and that despite the vehicle being relatively new, the promised multimedia and smartphone integration functions cannot be used at all. I contacted the authorized service in Ankara about this issue, but I could not obtain any effective or satisfactory result, and I was instead faced with a general attitude that the warranty has expired and that expensive part replacement would be necessary. I do not accept that the expiry of the vehicle’s warranty is used as a justification in a situation that is clearly a software and compatibility problem. A global brand like Hyundai should not leave its customers dependent on third‑party applications that are no longer supported and that render a factory‑installed system functionally obsolete. I kindly request that, instead of offering costly part replacements with the excuse that the warranty period is over, this chronic software problem be solved and that a software update compatible with current phones be provided for the multimedia system, preferably with Apple CarPlay/Android Auto support if technically possible. I expect Hyundai to take responsibility for this technical defect and to offer a solution in line with customer satisfaction.
