my 2005 rx330 does not have nav screen

I think it might be removed by previous owner.

so no chance unlsess I got nav screnn?

 

According to the Lexus Bluetooth page above you must have a navigation screen to connect with Bluetooth. Maybe your best bet is an aftermarket system. Check out the system Carver put in is 2005 RX, it's really a sweet unit:

NAV was an option. Doubt the PO removed it, more likely is that your RX did not come with it from the factory. You will need to add a 3rd party product.
