Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, bear with us; re-confirm and post back with the complete model number of the radio.

Still and in most instances, this would be caused by a sensor wire that is inadvertently touching ground. This wire is meant to be connected to a mobile phone that sends a signal when in use/incoming call causing the radio to auto-mute.
