I installed this in mine over a year ago, and it works great. Mine replaced my six disc changer because in 2019 I don't need six discs, I really don't even need the one in the HU. Ultimately the other options like the FM transmitters will be easier, but this one is really clean and sounds great, and you hear no white noise or engine whine ever. Steering wheel controls are maintained, you can pick up and answer calls from steering wheel, it's great.
