Does anyone know if this can be added to pre-August build RXs. I purchased my RX in February ... so obviously it doensn't have the ENFORM feature, however for the right price ... it may be worth the added features.

 

nope. it requires extra buttons on the the sunroof panel. And even if you can retrofit that part of it, there is no way of knowing if lexus would allow you to subscribe based on VIN
