What options do they have to activate the USB port in the consul of a 2015 dodge ram 1500 big horn 4x4 to play music from a memory stick or other device? Radio is RA2 model.

 

I may be wrong but I pretty sure its built as a charging port only so you can't change it. Upgrading the radio may be the way to go to get a usp input to the radio.. aftermarket head units are 3x cheaper than a factory unit.

 

A bit of off topic but is this article correct? https://appuals.com/flat-vs-curved-m...ich-is-better/

 

What does that have to do with the topic of this thread?
