Am looking to add Bluetooth to my 2009 Lexus 430sc. Any advice or products

 

You allready have it . Just have to pair a phone with it

 

As mrblister stated you have ability to pair phone via Bluetooth to make and receive calls

If your looking to stream music via Bluetooth this is what I am doing this week

$150 Installing a vaistech.com SC2U for 3.5 mm stereo aux audio input jack in center console
$50 Blackberry Bluetooth Gateway (ebay or amazon.com)
$13 Mediabridge High Output Dual USB Car Charger (amazon.com)
$5 StarTech 1-Feet Mini USB 2.0 Cable - A to Mini B (amazon.com)

It should be simple:
Plug the charger into the 12 volt in the center console
Plug mini USB cable between charger and Blackberry Gateway
Plug the 3.5 mm stereo cable into the Aux input in the center console and BB Gateway
Close the center console so everything is hidden.
Hit CD button on radio until AUX is displayed

Pair the phone and play away wirelessly.

The Blackberry will only stream music and not phone calls. The phone calls still should go to the car's ML radio via bluetooth.

The Mediabridge High Output Dual USB Car Charger has a second USB charger port that can charge an iPhone or even an iPad if needed.
