radio code and battery

[Peter D.H.]

Hello everyone,

I am a new member here. I have questions (they may be silly) related to radio code and battery change.

1) How can I keep radio setting when I change new battery ?

2) My Camry has wiring noise in the back (I think at anten area) when I press radio ON. Is that is that the code failure or some other problems?

Thank you very much in advance for all your helps.

Regards,

Peter
