Based on that, I did an Internet search and found this:

I'm sorry to be such a pain and keep asking about this. I just yanked my radio, and it has the same model number. 7305841.

That first link that you sent (thank you) has 7 search results for that model number. Do you know if there's a difference? Obviously, I'm looking for a troubleshooting/diagnosis/repair manual/guide. Maybe these are just schematics, and the troubleshooting is up to Google and me?

Thanks again for the links. I really appreciate it.
