2017 baleno radio not responding
 

I own a 2017 suzuki baleno which came with a bluetooth compatible radio (standard right?) The problem is when i connect to the radio with my phone and then disconnect the radio usually becomes unresponsive for a bout a day, meaning the volume wont change, i cant switch from cd to radio to bluetooth and i cant change stations etc. This time around it hasnt been working for 3 days now. Any idea on how to fix this?
