The In-Vehicle Infotainment (IVI) system replaced traditional car radios, offering a centralized platform with a larger screen and advanced features. Designed by Continental AG multinational corporation specializing in car multimedia systems, modern IVI systems integrate data from various sensors for enhanced functionality. As IVI systems are becoming more complex, their design is also becoming more intricate. Testing tools are crucial for verifying these systems; however, an inadequate understanding of the testing equipment can lead to a rise in user complaints. Therefore, IVI manufacturers must provide testers with user-friendly, effective, and efficient tools for addressing this problem. A survey involving 21 participants, including IVI tool users and resident engineers, was conducted to assess the user experience (UX) regarding the existing tool and the proposed tool. The participants completed two pretesting processes which were meant to evaluate usability, affect, and user value, with a total number of 18 sub-categories. The collected data was analyzed using a simple linear quantification model for UX, with the results indicating that this model could effectively translate UX into a single value. The proposed method highlights the usability and overall value of the IVI testing tools, enabling manufacturers to improve their systems to meet the testers` needs and reduce user complaints.
