Question about Car Audio & Video
Per page 26 in the following manual: http://www.sirius.com/pdf/manuals/kdcx679.pdf
The security code can't be changed, once it's set. Did you go through the sequence of steps on page 26 of the manual?
If you did (in fact) lock in and approve a security code, you'll need to contact Kenwood support and prove ownership (e.g. receipt) before they can give you instructions for resetting the code.
There is a hack for the ASIC that stores the security code out on the Internet (use Google to find it).
If my response helped you, please reward me with positive feedback (Fixed it!). Thanx!
