Hello, its possible that changing the battery either blew a fuse or locked up the radio, do you have the command big screen system or the smaller base radio?
Customer: replied 1 year ago.
I don't know the difference
Customer: replied 1 year ago.
I guess it's the smaller base radio

the fuses we need to check and pull out to see if we can reset the radio are the following, fuse 28 in the left side of the dash, it will be the 4th one from the bottom of the left row, it will be a 25 amp fuse it should befuse 6 in the fuse box on the left side of the trunkif those are ok then we need to pull the radio and check the fuse on the back of it. its pretty easy to remove if you are handy, let ,me know what happens.
