I have an '02 rx 300 and I don't have the navigation. I would like to do a swap out but I want to know how everyone likes the navi for this vehicle. Thanks guys

 

Adding factory nav to a non-nav vehicle is going to be tough. It can be done, but there is a considerable amount of labor involved, not to mention the expense. If you need the nav function, consider an aftermarket solution, such as those stand-alone systems available from Garmin, or Magellan. These offer more features, newer technology, simpler installation, and a much lower cost.
