I'm looking for a manual (in English) for a Xanavi Multi AV System for a Nissan Primera Hyper CVT GT6, or a CD Rom Map programme disc for this system. Can anyone help ?? Screen keeps going blank for long periods of time, or comes up with messages (in Japanese) to either 'Don't change key position" or "please change programme disc". As the air conditioning etc is controlled by touch screen control this is very frustrating. A Japanese manual would do, as we can get someone to translate for us.
