Hello, I have a Nissan Murano 2009, regularly serviced and well maintained. A couple of months ago, the addresses newly entered in the address book started to be erased as soon as i would turn the engine off. I have to restart from scratch entering the Home and destination addresses. I was told it was probably a battery issue. Since, I changed my car battery a month ago. Now the problem is worse as the phone selection would also be erased. I have to re-pair my iphone each time I take my car.
