I didn't want to waste time or money on the factory Bluetooth option after I noticed the 5 second delay on my Outlander GT. I have the base stereo in my 2015 DE and make use of the aux port and a 30$ Bluetooth reciever. I have almost no delay at all and it pairs instantly with any of the 6 different devices I use for audio or navigation. The sound quality is still a million times better than the crappy radio tuner. Even with this head unit I have installed 2 amplifiers and feel the sound quality is better than any factory stereo from American car manufacturers.
In short. Go on Amazon and spend 15$ on a Bluetooth reciever and call it a day.
