My question and problem is: On the touchscreen after I install a Audio USB or iPod. Since I have had the truck for only 6 weeks and HATE to read. I see the "SHUFFLE" icon and the "REPEAT" icon. In the manual if says when the SHUFFLE button is pushed it stays on until it's turn off. (when what's turned off?) I turn it on after keep hearing the say artists playing, but when I go and start the truck again. I have to push the SHUFFLE button again. It is me or the truck?
