I need to find a good audio integration kit that provided high quality music streaming and also handsfree phone for both android and iPhone. I know of gromaudio. My sister purchased it for her car. I noticed there is an echo issue when she is on the phone. I can hear my self when I call she is using this device in her car.

Is there anything other device that provides better quality for both phone and music streaming ?

 

Grom's the best for the bluetooth and handsfree add-on, so the next step up is an aftermarket radio.
