I just installed front and rear dashcams, which was quicker than expected.
Be careful when laying the cable for the rear camera! The airbags are located at the top of the roof, so lay the cable behind the airbags on the metal and secure it with strong adhesive tape if possible. Do not lay the cable in front of the airbags!!
By the way, you don't have to remove the entire cover under the steering wheel; just take out the small flap, and the fuses are behind it.
I have no problem with USB-C. The dealer gave me two A-to-C adapters, and my Android Auto WiFi adapter also has A. My mobile phone with QI charging goes into a separate QI charging holder, where it is cooled by the ventilation and a small fan in the holder. In the original compartment, it gets very warm, especially now in summer.
