I have a 2008 RX350 with the factory stereo without NAV.
I want to replace it with an in-dash system with NAV.

I am a newbie and not familiar with all the technicalities. SO please pardon my ignorant questions.

Do I go for a double DIN or a single DIN system?

Will something like this work and fit in my vehicle?

You will need a double DIN for sure. Also you will need a trim kit and Beatsonic wiring harness along with your double din kit. VERY important, if you plan to use the Beatsonic harness ie plug and play you must set all of the factory radio settings ie fade, bass, ect to neutral settings. Ask Beatsonic about that. If you don't then the factory amp will "remember" whatever you had it set at and sometimes cause problems. There are several great threads on swapping out the factory radio for a double din one of the best is by poster CARVER.

Welcome to Club Lexus, cyclotron0.

This is a topic well discussed previously here at CL. Best to just read the past experiences of others who have proceeded you down this path. You can get this to work, you just need to get the right parts from the right folks.

If you have a 2nd Generation RX and wish for a more modern upgrade, you can replace the existing cassette/CD/AM/FM receiver as done by alchemist, Carver, 1koolfella and others. For any of these systems you need to purchase the Double-Din faceplate along with the adapter cables to plug into the existing wiring harness and provide access to the steering wheel controls. First, you need to read Carver's writeup:

Be sure to read all the way through this as there is also a writeup from 1koolfella who has a setup with the existing NAV. Not relevant to your situation, however, it is good material.

Then, Packrat1's writeup:

Finally, the cheapest receiver replacement would take the form of the following from CJG:

There is a post in that last thread from RX330iPad showing his setup. More of its start here:

There is plenty more here at CL if you care to search.

Sorry, was how I copied and pasted the info. Found another thread with some comments of mine which not the same as previous are a bit more extensive.
