Seeking Tips on Retrofitting Front and Rear Park Assist in My Chevy Silverado

I’m considering adding front and rear park assist systems to my 2020 Chevy Silverado, and I’m looking for advice from anyone who has gone through this process. I want to hear your experiences, suggestions, and any tips you might have! Here are a few questions I have:

1. What Parts Do I Need?

I’ve seen various listings for kits online, but I’m not sure what specific components are necessary for the retrofit. Should I go for OEM parts, or are aftermarket choices just as reliable?

2. DIY vs Professional Installation

For those who have done it themselves, how difficult was the installation process? I have basic mechanical skills but I’m not sure if I’m up for wiring and coding the system myself. Do I need to have any special tools?

3. Troubleshooting After Installation

If you’ve already gone through the retrofit, did you experience any issues post-installation? I’m particularly concerned about compatibility with existing systems and any error messages that might pop up.

4. Cost Estimates

What did you end up spending for the whole process? I want to make sure I budget properly, whether I do it myself or go to a shop.

Additional Thoughts

I’ve read a few guides and watched some videos, but they often seem too generalized. If anyone has detailed steps or a checklist of sorts, that would be super helpful! Also, if you have any recommended resources or forums specifically for GM modifications, please share.

Thanks in advance for any help you can provide! I’m eager to make my truck even more user-friendly, and I appreciate any insights you have to offer.

I’m considering retrofitting a GM Park Assist system as well! From what I read, you’ll need the control module, sensors, and wiring harness. A good set of tools, including a multimeter, would be essential too.

3

That sounds like a solid plan! Also, don’t forget to account for calibration after installation. It can be a bit tricky if the sensors aren’t aligned properly!

4

I’ve heard that the installation can get quite messy with wires and connectors. Make sure to label everything as you go! Any specific models you’re retrofitting?

5

Good point! I’m looking to retrofit a 2017 GMC Sierra. I’ve read conflicting info on whether I need a special diagnostic tool to finish the setup.

6

A diagnostic tool could definitely help! Most likely, you’ll need it for making the final adjustments. If not, check the forums for any DIY calibration techniques.

7

Let’s not forget about the cost of parts! I’ve seen prices vary a lot online. Have you all set a budget for this retrofit?

8

Absolutely, I’m looking at around $500 to $700 for parts. Might also need to hire someone for the calibration if it’s too complex.

I can totally see this being complicated. Make sure you have a friend to help you! More hands make lighter work, plus someone can hold the tools when needed.

10

Great idea! I will definitely rope in a buddy. While we’re on it, what common mistakes should we avoid during installation?

11

One big mistake is rushing the wiring. Take your time, double-check connections, and follow the wiring diagrams closely. That’ll save you from headaches later!

I’ve been following this thread, and I love the enthusiasm! You guys are inspiring me to consider a retrofit for my Chevy now. Are there any tools that are absolutely necessary?

Definitely, a good torque wrench and wire strippers are must-haves. And maybe a few choice words of encouragement for when things get frustrating! :joy:

14

I can’t express enough that patience is key! You might face challenges with the wiring, but it’s all part of the journey. Take breaks if you need to!

15

Agreed! It can be a lengthy process but remember, the end result is worth it. Do you plan on documenting the entire process?

I think documenting could be fun! Plus, it could help others who are also trying to retrofit their systems. Let’s keep the updates coming throughout the project!

Hey! If you’re looking to retrofit the front and rear park assist, 2013-2018 models like the Chevy Equinox and GMC Terrain might be a good start. They often have compatible wiring harnesses.

18

That’s great info! What about older models? I’ve got a 2010 Cadillac SRX—would that work?

I think the 2010 Cadillac SRX can work, but you may need to do some wiring modifications. Check if your model has the parking assist option available in the harness.

Thanks for the heads up! Any idea where I could find a compatible wiring harness?
