I have an 2002 Infiniti QX4 with OEM Navigation. The Nav and Climate Control are integrated into the same unit in this model. Recently the backlight in the display went out. I did some research and found a lot of people remove the OEM unit, but you must get a climate Control unit from a car without Nav to make this work. The '05 updates to the maps work just great in my state and I wanted to keep the OEM Nav, so I continued my research. To make a long story short, the most cost effective way to fix my car was to have a custom CCFL lamp made to replace the dead one. The total fix cost me about $160 which was the cost of a minimum order of 10 custom made lamps. Now my Nav unit works again and I have 9 spare lamps for the backlight. I do not know what models or years this particular lamps fits, but I do know it is the correct one for a 2002 QX4 Nav/Climate unit. If anybody needs a backlight, I will sell the ones I have for $25, shipping included.
