Lately, my MP52 will occasionally switch back and forth between CD and Aux (which I use for my Belkin CarAudio Connect bluetooth to connect to my cellphone). There is no CD in the player, so I can't figure out the reason it wants to keep taking me to that setting. I use this player to listen to audiobooks while I drive. I removed the flip/release panel, opened it up and thoroughly cleaned everything. That seemed to help a little, but it still cycles back and forth on occasion. If I turn it off and then turn it back on, it seems to work properly a little longer. I have set the SRC button to Aux. What might be causing this, and what can I do to fix the problem?

 

It seems to have stopped within 48 hours after I cleaned the inside of the flip/release panel, though, not knowing what caused the cycling, I can't say whether it might return. Any suggestions would be appreciated.

 

It cycled again today, but only once, so the problem has not disappeared.
