Radio and steering control issues

Hello, I am looking for some thought on an aztec issue. I recently put a new battery in my wifes 2001 Aztec. I pulled the old one out and put the new in the next day. Now the radio jumps from station to station and the control on the steering whell do not work. I have been reading about the BCM. Is there a reset or anything on it. Does anyone have any thoughts on this one? Thanks
