<font color='#000000'>my cdx-m600, kepps on flashing--"ATT ON", and muting my sound, even though i am not pushing any buttons.  It seems to do it when i hit a bump or go around corner but not always.  I dont have the remote, and i was wondering if the only way i can fix it is with the remote?  please email me at 
pyxisokapi@yahoo.com  with an answer or suggestion if u have any, thanks  or, just reply.</font>
