Are all TPMS compatible except for the 07's?
 

Does anyone know if the TPMS can be used and reprogrammed on any 03-06 350z? Or would I need specifically the same year TPMS?

Also, is it true that I can only program one set of TPMS at one time? Or is it possible that I could throw on the aftermarket rims or the stock rims and the TPMS will work?

They are all compatible, including the 07 sensors. The 07 cars don't show the pressure in the multi-display, that doesn't mean that the sensors aren't transmitting the pressure.

Recently, friendlydacat has confirmed that sensors from an 07 work fine on an 05 car. There was another poster here who stated that old sensors worked on his 07 car.

thanks. Do you know if more than 1 set of TPMS can be programmed at the same time? I remember reading somehwere that you can only program one set at a time

This is very strange. I purchased a set of pre-07 G35 coupe sensors for my 07 G35 coupe's after market wheels, and the dealer was not able to program the sensors to my car. :confused:
