Due to your battery disconnection the radio is asking for its anti theft code. You can try looking in your owners manual for the new code, i found mine in there, the dealer will scrible it in with a pen usually. If not, then you have to go to the dealer to retrieve your radio's code. They will need the VIN no. to look it up. Also, some dealers require some verification of ownership before they will give you that info, be prepared!
Good Luck,
