Is there an A2DP solution that allow the steering wheel controls to work?

I have a 2012 ES350 loaner and the built in Bluetooth streaming is very nice.

 

There this Grom audio kit that works from what I heard http://www.gromaudio.com/products.html. You'll need to buy the bluetooth module from them too.

 

Just have not bitten the bullet, but this is the way I will go, no BT streaming, but the sheer functionality of using the NAV screen is a major plus over the BT stream.
Down side...$500 BUCKS!

I ordered the grom. We'll see how it goes. Thanks for the advice.

 

i use the dice mediabridge, got it on sale from walmart over Christmas ($180). Takes a little bit of time to get used to, but now i like it a lot. I got it for bluetooth and usb functionality, but found that i usually use the usb option as it sounds much better than bluetooth.
