So I was told about this "memory stick" you plug into the cigarette lighter and it won't erase the memory from the car when you disconnect the battery. As in radio channels, recorded miles driven, etc. I just don't know what it is called or where fm start looking for it. Can anyone help point me in the right direction where I ca find this? Thanks in advance.
