Is there a suitable replacement for the G80 high beam headlights if they're not bright enough?

I'm looking for some advice here. After the system update, my navigation keeps reporting a camera issue. Before, I could just turn down the volume, but now every time I restart the car, the volume goes back up. It's really frustrating. Previously, the CarPlay navigation and system volumes were separate, but now if I turn down the system notification for the camera, the CarPlay navigation also loses sound. Any solutions?

The BO system in the G80 is said to have 18 loudspeakers, but when I count, it doesn't seem like there are 18. Also, the two loudspeakers under the rear windshield don't seem to be working. When I set the soundstage position to the center and sit in the back row, the sound still seems to come from the front, and the two loudspeakers under the rear windshield don't seem to be functioning.

Does the G80 have a serious interior odor? How is the quality of the materials used inside the car?

Is the rear space of this car spacious enough? I'm 1.87 meters tall. How does it compare to the Volkswagen Passat?

Has the rear space of the new G80 model increased compared to the old model?

Does this car have a comfort access system?

Where to get maintenance?

How to repair and maintain if there's no 4S shop locally?

Yesterday I test drove the G80, and today I tried the E300L. I tested both cars on the highway. The G80 has better sound insulation, its engine sounds good and powerful during sudden acceleration, and it feels resilient over manhole covers. It gives you the urge to drive as soon as you get in. The Mercedes E's sound insulation is slightly worse at speeds of 80-120 km/h, and the engine roars loudly during quick acceleration. The brakes don't inspire as much confidence (they feel a bit soft). The seat comfort is similar for both, but the G80 has better support.

Does your car have the issue where continuous driving over dashed lines causes high-frequency vibrations to be transmitted to the steering wheel? I'm a bit disappointed that this kind of problem occurs.

Can I go to the Hyundai 4S shop for maintenance? 😂

Does this car have a particulate filter installed?

How well does the car's adaptive cruise control work in traffic jams? Is it practical? I'm only interested in its performance in traffic jam situations.

How is the all-wheel drive performance of the G80? Can it handle rainy and snowy conditions easily?
