The question is...why would you want to retrofit and go with the (direct) RDA tire monitor system with sensors in each tire? It's paying money for sensors that basically do the same thing as the RPA (indirect) system...plus the headache of replacing the sensors when the batteries die...and making sure the sensors aren't damaged if you have to replace a tire.

This is the indirect RPA system description:




Below is a chart that shows some of the models that had the DIRECT RDA system and some that had the INDIRECT RPA system:
