Due to the new hands free State law I needed a device to answer the phone in the car. I tried two different Bluetooth devices that required tuning to a fm frequency. They were difficult to use and didn't work. Found the Crux unit and thought I would give it a try as it sounded very close to factory Dodge Uconnect. Installation was very easy, removed the radio, connected the Crux inline and reinstalled the radio. Now I can answer the phone by pressing the tune up button on the steering wheel. Great sound quality sending and receiving. Could not be happier. Expensive option but it works and works well. I highly recommend this product.
