Saving Settings

2 posts in this topic

I need to disconnect the battery on my cmax. But i dont have a radio code.

Is it possible to save the radio and engine management settings by connecting the leads to a battery charger before disconnecting them from the battery ?

depends why you need to disconnect the battery, you can use a battery saver which will allow a tiny trickle to keep these alive, but it really depends on the overall purpose.
