Legacy help................

[donk r8]

Hi guys, I picked up the legacy this morning and said goodbye to the Patrol but on the way home the sat nav/radio went black and the word security came up. The cd still plays but cannot turn it down or eject it!! The supplying dealer hasn't a clue and I cannot find anything in the manual, it it anything simple..............please..

sorry its an 08 outback..........2.5
