Hello, I have a 2012 LX civic 4 door car Id like to swap from factory radio with out the bluetooth phone option to the premium sound with the bluetooth button. I have ordered it and have it now. Says PHONE ON THE FRONT LEFT LOWER BUTTON. IS there anything else I need. I have read that it works but cant remember where I saw the post or thread. Hoping theres not anything else I would need and this is a direct plug and play upgrade.
