What is with the phone mute on my concertclass radio

Customer Question

What is with the phone mute on my concertclass radio whenever I put my peterbilt truck in reverse?
JA: How old is the phone?
Customer: That's just it-there's no phone connected to the radio. I looked in the radio user manual and they give no explanation for this 'phone mute' foolishness whenever I shift into reverse and I'm trying to figure out how to get rid of it
JA: How long has this been going on? What troubleshooting have you tried?
Customer: Since I first got it in Sept.this year. I've tried everything I could think of and nothing gets rid of it. It's driving me crazy. If I touch the volume knob right after I shift into reverse it comes back on but that's annoying. It serves no purpose at all and I just want it gone
JA: Anything else you want the electronics expert to know before I connect you?
Customer: No I just hope they know what to do about this

Hi, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, is the "...concertclass radio..." factory installed or an aftermarket?
