I have a 2009, ideally the aux in would be the preferred way. I have not taken apart the center stack yet. Are there rca jacks in the back of the head unit to plug it into?
No, the only way into the factory system is through adapters.

Can you post photos once you do this please. In every other vehicle I own I have always swapped everything to JL audio so I would like to use this adapter but I am not in anyway an electrical person but if I see a photo then I can get it done. I can live with the rest of the system the way it is but really want to be able to bluetooth music to the vehicle.

Thank you in advance.

Cheers

Nothing to see, really...the JL adapter needs switched power which I tapped off the back of the lighter, and it plugs into the AUX-IN port in the center console. You can see about 5" of the 3.5mm audio cable I snaked in from behind the dash.

Just a quick initial review of this setup so far...

- If you go this route, make sure to set DIP switch #2 ON thereby selecting 4v output, the 5v setting adds a lot of hiss creating a high noise floor. The ML head unit goes to 60, but I like my max volume to be 75% of whatever the head unit goes to, so 45 is my max. With gains set to accommodate this result, hiss is quite prominent on the 5v setting.

- The PAC Audio adapter provides the Remote Turn On signal, but it goes hot whenever the key is ON, it does not turn on/off with the stereo...kind of a bummer as that leaves the amp sitting ON even when the stereo is OFF...

- I have a 5 channel amp utilizing 6 stereo channels. The PAC Audio adapter has Front/Rear/Sub outputs with a remote volume control for the sub channel. Using the sub inputs for the sub channel results in very little bass even with the gain, boost, and volume remote knob all the way up. When I switch to "internal" for the sub channel, which sums channels 1-4 and feeds the sub channel from there, the sub output is roughly 3x as much, even with the boost all the way off. This renders the remote knob useless. The PAC Audio adapter needs to be USB plugged into a laptop for setup and I have not done so yet, I am hoping there are some internal gains or other settings that allow me to tune the sub channel some more...updates forthcoming...
