As an elderly person, I wish there was a slower explanation so we could absorb the tech info at a slower pace. Overall coverage of subject is good. That radio tech info needs to be explained slower for senior citizens. That would be a big help. This is better than the manual explanation.
You can try changing the playback speed to 0.75x instead - that would slow things down. Also check out these more recent videos where I'm speaking slower and the audio is better: Sync3 Screen - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hj1jVDYDYzI.html Steering Wheel - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cUAtFKQbUO0.html
