I found this video interesting...Will it work?

there is an option to disable the theft lock in the manual so you dont have mess with it in the future if your battery goes dead or something

I could never get that procedure to work to display any numbers, the radios were the same model number, however I went out and put the old radio back in and it works perfectly go figure, guess it just needed a little attention.

Excellent news!
Thanks for the update. I am glad you have a working radio again!
