I have an 05 Shinka with the built in Sirius radio. All has been working well with it for almost two years. Recently, I had to take the car into the dealer for service. They had to remove the battery and thus I lost all my presets. While trying to set them back up, I have about 10 channels that show LOCK when I tune them in. These are not premium channels or anything like that, just normal music channels. Sirius says that a parental lock sounds like it is enabled, but I can find no reference to that feature anywhere in my manuals. Can anyone help me out here? Thanks in advance...
