we have a brand new 2021 Pilot and the sound system is messed up. When the radio is on, it skips, like a scratched cd. But it’s not the radio station. When the sound is turned down you can hear snap crackle and popping under the dash. Like a loose wire. Or who knows...a computer glitch? We took it to the dealer, but of course it worked fine. I just don’t want the whole thing to go up in flames. Any ideas?
