Thank you for that 20 years. It is people like you who have made my life more complete because the audio and video systems in cars have made major improvements.
As for information about the F-150 and B&O on YouTube, not so much there. Part of the problem is that the music industry is very protective of its copyrights. If one uses music that people normally listen to in demonstrating the function of a device, an algorithm blocks your YouTube video. If you couple that with the fact that folks who do YouTube videos about cars while they may know stuff about autos, they are not audiophiles. I do not claim extraordinary knowledge of audio, but watching the YouTube videos about AV systems in cars usually generates more questions than answers from my perspective. So, why is this important.
I think car manufacturers watch the reviews of their autos on YouTube and will from time to time make changes based on what they are seeing. Naive - maybe, nevertheless, if more audiophiles would do reviews of the entertainment systems the manufacturers are putting in their cars, things might improve. At the least, some of my questions would be answered.
For instance, if the B&O system is 7.1.2, why no Dolby or Atmos. Apple music is doing some great stuff with Atmos. What about Dirac in cars. I think it's available. I do not find YouTube videos about it. The answers to these questions could be the additional cost to add those features, or the car makers assume that most people don't care about that stuff.
As for your statements above:
"How much does an aftermarket system or upgrade cost?
Will it cause problems for the warranty and operation of the vehicle?
How much better will it be?
If the answers are:
A lot- more than $2000,
Probably or yes,
Somewhat, but it won't be ground-breakingly better,
I wouldn't do it. OTOH, I wouldn't really want to pay $3K for the OEM upgrade, either."
I agree with you, and that is why I ordered the pickup with the B&O system already installed.
