    pioneer deh-740mp, PROBLEMS !!!!

    ok i have a pioneer deh-740mp head unit. its in perfect shape with no scratches on it, when i first got it it worked flawlessly, but here recently when it gets warm it'll shut off. like you can be ridin around for a hour and it will work perfect, then if you just hit a bump in the road it'll shut off. completely. it looses all my presets for the audio, the amps shut off, clock resets, everything just like u pull the power wire out of the back. so i ran a new constant 12v wire to it b/c i thought that was the problem but today on my way out of town it shut off after about a hour of listenin to it. it comes back on like it always did but the slightest bump will cut it off again........ any input would be appreciated. thanks,

    are you sure that the connections in the back arent loose?

    maybe the port is bad and whenever something hard hits it moves the slightest bit and loses the connection.

    bad/loose ground would cause the same problem.

    Re: pioneer deh-740mp, PROBLEMS !!!!

    ive checked everything!!! rewired all my connections and there all tight, the wires are put together with wire connectors, not lazy cheap *** electrical tape, and crimped, everthing is tight..... could it be something internally ?

    it very well could be internal, maybe a loose solder joint.
    Any warranty on it?
