2001 C70 convertablew with the surround sound system with 3 cd changer. I replaced with a new stereo with Iphone and pandora and bluetooth so I can talk hands free. Now whenever I put the key in the ignition, it chiles like the door is open, which it is not. The factory stereo had a security code and I wonder if the car thinks it is gone and needs something done to say it isn't coming back. Has anyone else experienced this?

 

Ok you ADDED the BT and Iphone adapter not replaced the entire system..Right?,......if you did it is possible you connected something wrong to the ignition switch. Pull the radio fuse and insert key...if it does not go off then you connected something wrong...I do aftermarket on all my cars so not sure what/how you added to OEM!
