Yeah so I have the CR-220 OEM radio in my cab. I just noticed right now the red light on the face is flashing once the key is out of the ignition.

I can swear it ever did that before....or am I crazy and it has been flashing all this time and I just noticed it now?

anyways..anyone know why it is flashing?

 

it's trying to tell you to read the manual

 

I know I know...RTFM...
but hey its late and who the heck has time to read the manual. I even did a search. Figured someone would know the answer much quicker then my *** walking back down to the garage to read my manual.

 

I wish I could help you but I haven't RTFM either!

the least I can do is bump your thread....nudge....

 

Yes, it has probably been on the entire time, but you can turn it off through the settings menu. To learn how to do that, RTFM.

 

Fine you guys are going to force me to read the manual....

once I have the answer I will share with the world on this thread to save someone else the headache!

 

While I am not 100% sure, I believe that it is letting you know that the anti-theft feature is active. "Don't remove power from me, or you will have to find that damn code again".
