I just got my 04 TL back from the shop. I guess they disconnected the battery because I had to enter a pw to get my navigation working again. I'm pretty confident I entered the right # however now I cannot access my audio content. the word "code" appears where my radio station should appear in my upper display, anyone know how to fix this?

 

There are two codes. one a radio and the other a nav code.
i think you use the station presets to enter in the radio code.
