Just acquired a 2007 RX400h. How can I bluetooth my Samsung7 to stream audio for Google navigation and Spotify? Do I need an after market workaround? Sorry if I am asking the obvious but I had a 2014 Avalon and am used to all these conveniences. Thanks!

 

I have this in my wife's 09 RX350 and it's been working well for a few years now.

 

You can't without an aftermarket interface. There are a number of existing threads on options that people have used.

 

Remember you have a 2014 phone trying to connect to a 2007 vehicle. Yes, theoretically blue tooth is blue tooth but each device has to be tested and verified that it can pair. Product cycles for vehicles are much much longer than phones so they cannot plan for something made 7 years in the future.

Now having said that if you buy a newer aftermarket radio chances are it will work with your newer phone.
