I am planning to change my Nissan Almera car radio by replacing it with a Sony CD player. I was wondering that before changing the radio, do I need to disconnect the negative battery or just go ahead and open up my dash panel to do the work?
If i have to disconnect, then I am worried about the pin codes as I do not have any codes with me. Will disconnecting the negative charge erase the pins? If yes, where do I get them from and where do I enter them?
PLease advice. Thanks|||to b on the safe side, yes u want 2 disconnect. even though i hav done without disconnecting many times.....
