i have an 09 access cab sr5 and the auxilary jack has plain and simple..**** the bed. ill go over a bump or something and the radio will go out of AUX and start playing the cd. also, it only plays the passenger speaker and when you move the wire it plays everything, or just shuts the deck off.

any suggestions to fix it?
how much is it to replace?
is it under warranty if i only have a little over 30k on the truck?

-thanks
