Jvc Car Radio Why Does My Newly Installed Jvc Car Radio Keep Going Back To The 87.5 And My Clock Not Remembering The Time?

Why does my newly installed jvc car radio keep going back to the 87.5 and my clock not remembering the time? - jvc car radio

Radio works fine, except that he did not recall that I listened to the station and time on the clock until 1:00. If you parked the car and immediately returned to this problem does not occur
