I am in the process of installing a factory navigation in my 2010 Nissan Maxima S. I got the complete navigation system (Navigation Display, Switch Assembly, GPS Antenna, 6-CD changer w/ AC Controls, and rear view camera and bluetooth mounth with all wires. But I came into a major roadblock the main harness in my car is different from the harness with the Technology package. To order the Technology package harness I will have to buy part number: 24010zx74C from Nissan or OEMparts online which is around 620.00. But once I am finished installing I will let you know if there is any other roadblocks I encountered.
