Wow, I installed a car navigation system in a place like this!

Where is your external car navigation system installed? I think it's mostly on the dashboard, but if you're sitting low, it's dangerous because it partially blocks your view. For such people, I disassembled the room mirror and integrated it with the car navigation system. There is a sense of incompatibility at first, but once you get used to it, you can use it without problems.
If you are interested in the self-made items that appeared in the video, please take a look.
