I had the battery changed on my 07 Titan and lost my radio presets. Now, here's the problem, presets 1-3 are now set for FM and 4-6 are set for AM and I can't figure out how to change that. When you go to, say, preset 5, which is AM, and push the FM/AM button, it sends you to preset 3. It won't change from AM. Same with presets 1-3. Push the FM/AM button there and it sends you to preset 4 (AM). It is the same for all three channels (A,B,C). Has anyone had this problem before and how do you fix it? Thanks.
