Changed the whole adaptive cruise and lane assist, it's just amazing. No more having to nudge the steering wheel every ten seconds.

I had this installed and rolling out the garage door to complete the calibration before the UPS truck left the neighborhood! Let the good times roll!

I’m really impressed with the comma four on my 2023 Ram 1500. I was pretty nervous about it, but I decided to do the install myself and it was way easier than I expected. The cables routed so cleanly that it actually looks like a pro did it. The difference is night and day. Lane centering is now solid and stays right in the middle instead of hugging the right side. After a little tweaking with Self-Tune and a small camera offset, it feels super natural. The auto lane changes when I hit the blinker are smooth and work great. Highway driving is way more relaxing now. I can actually sit back a bit and enjoy the drive instead of constantly correcting. Highly recommend it if you have a Ram and want better hands-free highway capability. Still have to pay attention of course, but it’s a fantastic upgrade.
