Agree. And to coin a phrase, being this Truck is a Blank Slate, it will be much easier to build and install the audio system you want rather than mod a proprietary system from the manufacturer.To me, it's like, how much is it to install your own radio? Couple hundred? But have the company include it, and they charge what? couple thousand? Why are people insisting on this?
The 1950's called, it wants it Champions back...RFI in car radios is filtered in the radio, not the car. FWIW; RFI in greater in ICE cars then EVs. Spark plugs are noisy.
BUT YOU KNOW THE STATION HE WANTS to listen to will not be one of those 90,000...It seems everthing your write is negative. I suggest you consider that this might not be the right vehicle for you. An easy solution for AM/FM radio is to use your smartphone or tablet and subscribe to a service such as SimpleRadio. There are many to choose from, at a cost of $15-$30 per year. Not every station is available; only something like 90,000 national and international stations to choose from.
Correct, though it's not really "filtering" in the electrical sense, it has to be blocked through EM shielding. And due to the relatively low frequencies involved and the lack of an earth ground, effective shielding could add significant size, weight, and cost. There ain't no such thing as a free lunch, so those clamoring for AM radio support need to state how much they're willing to reduce range and increase price to get it.The RFI has to be filtered at the source where it is generated.
