    Hello,

    Weird problem, swapped out the copen stereo for a Sony head unit about 6 months ago, works fine but every now and then, like once a month, it seems to go back to factory defaults and loose all the presets.

    I have had this in the past when the power leads arent connected right but that would make it reset every time the ignition is off, this only happens now and then.

    It's like the battery is being drained or cant cope sometimes and stops supplying power to the stereo just long enough to reset the stereo.

    Any ideas?

    Thanks, Andy.

    Hi Andy,

    As you say, this is normally a problem with the constant 12v supply.
    The standard is:
    Yellow lead to constant 12V supply.
    Red lead to switched 12V supply
    Black to ground

    Does you car start ok? If so, it can't be a problem with the battery, although starting your car can take the battery voltage very low, but I think you would notice this with the slow turning over of the starter.

    I would try running a new constant 12V supply directly from the battery (it will need an inline fuse) to the yellow cable - disconnect the old cable! Maybe there is a a bad connection somewhere.

    How to pass cables from the engine compartment to the cabin...
    I've added the white and brown cables.

    It comes out behind the glove compartment, you have to feel around for it. From there it is easy to route it to your stereo.

    Hope this helps,
    Rex.

    Rex that is an excellent idea, normally im a bit nervous about running cables through the firewall but that looks fairly straight forward in your pic.

    Will give it a go when i get a dry weekend.

    Thanks, Andrew

    Just to say Andrew, you do need to pass a lot of cable through the bulkhead before you can find it inside (I think something to do with the air con is behind the glove box).
    The other option is to put a piece of stiff wire through first and point it it a downward direction.

    I don't remember having too many problems so if I can do it, I'm sure you can!

    Rex.
