Hello -I have 2009 ES350 with factory navigation, and need some recommendations to add bluetooth/USB music streaming kit. I am looking forward to hear from you guys with recommendations/links. Thanks.

 

I tried various bluetooth but couldn't stand the "buzzing" feedback when accelerating when the bluetooth adapter was plug in to the cig lighter. I wanted to install double din but just love the factory setup thus, I have aux cable with stupid apple 3.5 to lighting adapter.

 

This adapter will help you stream music from BT and USB devices, but it costs about $150 and additional installation cost, may be over 300 in total cost.

Trying to find some other cheaper alternative.

 

I did try cassette and AUX-IN BT adapters, but some constant buzz sound irritated me, so ended up returning them.
