Radio Issues

I just got a new 2015 International with Sirius Radio(company truck). The radio won't stay on longer than 1-2 seconds before immediately cutting off. One person said the wiring is probably screwed up and another said the radio is junk. I can't really afford to go sit for 3 days waiting for the dealership to fix it. Any ideas or advice?

 

I just got the truck last night and haven't really ran the engine other than to do a pti. It was shutting off while engine was on but I was thinking maybe battery is not fully charged. Not sure if that would affect it?

 

Actually I did take it for a 15 minute road test
