Interesting phone call, service manager quoted me 7k to install adaptive cruise control on my 2018 compass.... for non Trailhawk compasses, 1700 to change front ends to trailhawk with steel impact bar, they also have to calibrate the radar if it’s removed. Putting on bigger tires? 97 dollars to calibrate speedo, that lets you keep the warranty on everything. The ACC they said they have to change the body control module as well as the drive train module as well.

Do you have the front collision warning/breaking system (with the radar eye, etc)? I think if those parts are installed, the car should already have all the hardware required for ACC.

The dealership said they would calibrate the speedo for my compass, when it comes to the ACC, the manager was a major dick about it, saying yeah they could, but putting an outrageous price on it so that most people won't think twice. I told him I have the Forward Collision Warning Plus, he still said he would have to install new body modules and drivetrain modules and that apparently adds up to 7k.... No other dealership will look at it though, so i'm going to ask for an estimate lol. I'll keep people updated as I go, but for right now, i'm saving up to do the tires and front end swap and adding the skid plates. 2500 dollars later, i'll see where I am at lol.

You can ask for the part numbers as well. If they need to install a different body modules and drivetrain module, their part numbers should be different than what is now on the car.

For what I learn playing with AlfaOBD is that the body module is the same for all models. What it changes is the vehicle configuration.
In simple answer. Even with the new module. Jeep won't turn in adaptive cruise control. Because those functions are turned on by the VIN configuration.

In other words. Get yourself some AlfaOBD. And turn on the feature your self.

This is the route I'll be taking with AlfaOBD. Just working on other cars so not getting to it anytime soon.

I am 99.9% that what your dealer is asking for is wrong. There is no procedure for retrofitting the ACC, so he just made stuff up. I've seen this with my dealers up here a few times, but little did they know that I knew more about the car than they did ... sad ...

I'm willing to bet that as Jaime said, it just needs to be turned on, and maybe a module or 2 need to be flashed.

Haven't posted in a while. Been busy with other stuff. I bought the new steering wheel controls for ACC. Haven't got a chance to install them yet. Once I do, I'll enable ACC in the BCM and see if they work. My Jeep doesn't have the radar distance sensor, so that might be next if things go well with the buttons. At the very least my wheel wont have depressing blank spacers.

Hey n4cr2k, By any chance, do you have the part numbers for ACC controls.

I was impatient and bought the part for the Cherokee instead of waiting for the part number for the 2019 compass. The wiring harness looks correct and seems like it should be a drop in replacement. Just haven't had a chance to pull the steering wheel to try it out.

I am very interested in how this goes.
I have a 2018 latitude with the advanced safety package, so I have the radar sensor, (forward collision and lane assist).
Seems like all I would need is the steering wheel switches, and then enable it with alfaobd.
If someone can get this to work I certainly will be buying those and turning it on.

I have the steering wheel controls, I have alfaobd, and I have the advanced safety package. But with a US manual, they don't give us the radar. So I'll try to hook up the controls and enable it, but not sure if it will be a great test of its functionality. I'd add the distance sensor if i knew it would work, but its rather pricey at round $600 to try. I'm only out $60 with the buttons.

I took a go at it today, but couldn't get the airbag cover off of the steering wheel. Looking at other vehicles, it seems I need to use a flat blade screwdriver to release some clips. Anyone know of a good how-to or some tips? I probably just need to fumble around with it some more.

I found this video for a renege. He struggled a bunch, then finally got it. After he gets it out and undone, I wish he would put the screwdriver back in and show the clip/un-clip mechanism more clearly.

According to the link below. ACC for Compass only has 3 hardware components. The radar, front facing camera and steering wheel switches. Radar and front facing camera is already on the cars with collision warning system. There are some other parts as well, but those seem to be on every model with regular cruise control regardless of trim. So only hardware needed is the steering wheel switches (which as $39 according to the link). It will of course also require software activation. Even if the entire steering column is needed to be replaced for some strange reason, it will cost 189+39 (so say $300 after shipping, tax etc).

I feel like any dealer who intends to charge $7000 for this conversion is straight up scamming people. All they are going to do is disassembling the steering wheel, replacing the cruise control switches with a $39 ACC one and software activating it. It worst it will take 30mins for a mechanic to do this.

I finally found a good video that demonstrates getting the steering wheel cover off, albeit its in Portuguese. He shows the procedure around the 2min mark.

Don't expect there to be the plug for the ACC in the wheel. The car will most likely have a different harness. This means you will need to get the wiring diagrams and wire it up yourself. You will also need the male and female pins, and the male connector plug that goes into the ACC switch.

You will be adding the missing wires from the switch to the clockspring, and then from the clock spring to wherever the wiring diagrams say - probably the car's main computer module and the cluster.

It is not hard. I've done this sort of thing many times retrofitting equipment and functions to my other cars. But don't expect to just pop in the switch, as I am 99% sure there will be nothing to plug it into.

I've watched the video of the wheel controls being taken apart. The harness/connector is the same for both our current part and the new one with ACC. It's all one unit. I'm still struggling to get the airbag/horn cover off though.
