## 4 Discussion  
We summarized the 213 answers of the three countries for all the 24 questions (4023 answers). The results presented in Table 5 were also used for this summary. If at least two of the three \(p\) values showed significant differences, they were included in the final results. The results are presented in Figure 11. Hungarian is used in the illustration. \"Utca\" means street and \"Majd\" means then. For other terms or help labels, the English meaning is shown in gray. In line with the questions, we derived the following results:  
1. The device speaks the user's native language most of the time but cannot handle voice commands--even if it implements voice recognition, it is more common that drivers do not take advantage of this feature (Figure 3). 2. Most people use a perspective view (with the facing direction to the north). 3. Although it was not specifically asked what input method was preferred (just what they currently have), from Figure 4a, we can conclude that: (A) many people are bothered by the navigation knob (it makes it difficult to enter text); and (B) voice navigation is not widely used. Based on these questions, the touchscreen has been designated as the required input. 4. Since only a small percentage of users (~30) indicated that they are specifically bothered by the click sound when they select something on the interface, we concluded that users will also want this sound to some extent. 5. Most would prefer the current placement of the navigation interface. The top of the center console also received a similar percentage, so we marked it with a dashed line. 6. Users prefer the night mode and they usually check the alternative routes during planning (gray line in the illustration). 7. Although it is not connected to the map view of the interface, most drivers use history for frequently visited addresses (mostly addresses of family or friends). \begin{table}

Table 5: Results of the [PERSON]’s exact test. Significant differences (\(p<0.05\)) in red. Returning to the specific objectives outlined in the introduction:  
* What do GPSs look like today and what are they used for? In Figure 10, the currently used interfaces can be seen. Respondents have indicated quite a few features that they are seeing in their built-in navigation device. Only a few questions about usage have been highlighted here (see [54; 55; 56] for more). Based on these, it seems that even though the device incorporates many capabilities, most drivers use it to perform only a few basic tasks. * Do drivers consider these devices to be appropriate? If not, what would they prefer? Whether we look at the responses divided by country (Figure 10) or in total (Figure 11), it is clear that drivers want fewer features on these devices. Perhaps an even bigger problem is that because of the cost of the device (and upgrades), many people prefer to not use the built-in navigation device at all. The lack of traffic information--available for free on a phone app--is a major drawback to built-in GPSs.
