Need help with switching to non navigation climate control thanks

 

Not sure what you mean. The 5th Gen Maxima's came with either manual (analog) climate controls or digital. The navigation system that came with some of the 5.5 Gen's is a separate unit that should fit with either type of climate control.

Switching from Manual to Digital is not advisable because the digital control unit uses additional sensors that you would need to install, and it can be quite laborious.
