I forgot the security code

I read this on ecoustics forum:
You could try this:

When you are asked for the code, press and hold the 'AUTO' button and "Next Track" ">>|" for 3 seconds till the (----) disappear.

Now take the remote control and Type "KCAR" with the number pad.
PRESS "5", "5", >>| (NEXT TRACK) you should have a "K"
PRESS "2", "2","2" >>| (NEXT TRACK) you should have a "C"
PRESS "2", >>| (NEXT TRACK) you should have an "A"
PRESS "7", "7", you should have a "R"
PRESS >>| (NEXT TRACK) and hold for 3 seconds

If successful you will see 'Approved' and the stereo will go to standby screen

Good luck
