Navigation system not de-energizing following shut down of car
well the first thing we do is a battery hard reset. turn all off, discnt batt both cables wait 5min then reconnect. the reason both cables are discnted is so they will reach together after battery is disconnected. be very careful not to spark the battery. and always use battery bought from infiniti due to these large capacity battery's the dealer sells for around 100 bucks have additional reserve capacity (really important) not found in most batteries and they come with 84mo lmtd warranty that includes 12 mo of batt related roadside! buy and install yourself for 100 bucks.
