Subaru Outback 2010 Change of Radio

[Outbackman]

I have just fitted a replacement radio (Panasonic 86201AJ301) for which I have the Code, however the screen isn't asking for the code but instead is showing the word "Security" on the screen.

Nothing seems to activate a change of the screen. How do I get to input the code.

I have disconnected the power and the radio has worked but then after about an hour the radio goes off and reverts to the "Security" error showing.

Any ideas please

Thanks Graham

Did you ever find the proceedure?  I have exactly the same issue!

Hi, has anyone had any luck with this issue. I’ve have exactly the same issue and have been told it’s now internally locked and need to be replaced as there is no way around this point.
