Factory radio

When my D-3 was installed, the installers forgot to remove the discs from my factory radio. is there anyway possible for me to retrieve my discs from my factory radio, with taking out my d-3 and re-installing it? thanks in advance.

If your radio does not a manual eject you'll need a bench power supply.

Or just hook up the negative wire on your stereo to the negative battery terminal on your truck or any car battery and then hook up the power wires (the wire that turns on when the ignition is turned on and also the wire that needs power all the time) together to the positive battery post. At that point you should have power to your stereo and be able to push eject to get the discs out. Hope that helps!!
