Hey all, hoping you can help me with this. I have a brand new 2021 E-pro 12rk. It has the new iRV Technologies iRV36 stereo installed. I use a USB on my motorcycle and car to store and listen to music and noticed this stereo has a USB port in the front, as well as an HDMI port. So I got a USB and loaded it up with my music and can't for the life of me figure out how to play it. I think we all know that iRV Technologies website is seriously lacking so I can find no information there. Although it's a different model, I did download the manual for the iRV34 which says to play music from the USB, just push the source button until you get the display to show USB. I've tried switching through source and all I get is AM FM, Bluetooth, and auxiliary for the TV. Any help with playing music from the USB would be greatly appreciated. It should be noted that when scrolling through the sources, the front HDMI port also does not show up.
Thanks. Here's a couple photos. One of the stereo and one of the remote.
