I would first check and make sure all fuses are good in all fuse panels.If any are blown the affected fuses need replaced.If these are checked and found to be o.k. this may be an issue with the radio itself.I have seen some of these fail internally and in some cases a voltage surge from battery replacement can sometimes damage it to where it would need removed and repaired or removed and replaced.The radio will need removed to have the power and ground signals tested at it to make sure these are present.
