Radio usb specification

Anyone know what the type/size/format for a 2019 vnl860 factory radio?

Also anyone replaced the factory radio, upgrade sound system?

 

Anyone using the usb thumb drive for music mp3 ? If so what gb size are you using?

 

Thanks for the reply. I have over 400 GB of music media stored on usb thumb drives that I would like to listen to in the truck, but the factory radio says they are an invalid format. Most likely it has to do with the size or file format of the usb drive, that is why I am asking if anyone knows what it may be?

They play fine on the wives car , a 2020 ford escape that has a usb in the console.

The truck has blue tooth, phone connects to it. But my media is not on the phone, it's on usb

 

What is old to some is vintage to others- my collection of music is 7 decades, stuff you wont here on a streaming service, hours of DAT live and bootleg recordings, etc.
Ripped hundreds of CD's to digital storage, and have them on USB now. Then sold the CD's along with all my vinyl so in that respect I did " throw out" my old stuff I guess. Thanks guys.
