Car radio losing all the settings

[Peter Oll]

Hi!
My car radio lose all the settings when i shut down and then start the car. I don´t have this problem if i try with another radio in it. What can be the problem?

some radios require a permanent supply for memory retention.

i dont deal with car radios i just said what i know from experience, one more thing, if you list the make and model somebody who knows the set may read , without knowing the make and model chances are very slim that somebody would be able to help.
