This system was so easy to use and it works great! My son lost one key fob and broke the other one. It was cheaper to install this system than to replace one of the factory key fobs, plus it added remote start functionality! win for us!

Waste of time and money

First time dealing with Crutchfield has been proven a waste of time and money. I am a retired 12volt systems installer. I have literally installed thousands of remotes starts, alarms, competition sound systems, etc... I bought this remote start due to the brain-dead ease of the installation. However, after the installation it would not start. Throwing me a "hood open" fault even though all was correctly installed and no "hood open" was present. Contacted Crutchfield's professional remote start Technical Support. As far as I can tell they do not exist !!! All I got was several promises that a professional would call me back within a few days to assist me. As of yet, after several calls to open an issue, and after the promises of a call back, I STILL have had no return contact from Crutchfield. My next step is to see if I can return this starter.

Pros: None

Cons: Never got to work, Never received any "help" from Crutchfield's "help line".

Crutchfield response on 4/3/2023

Jesse contacted our Customer Support team and set up a return. Purchases from Crutchfield can be returned or exchanged within 60 days. We were sorry to hear about his experience with our Tech Support team. We're forwarding this on to our Tech Support supervisors, so they can look into it. We strive to provide the best service, before, during, and after your purchase, and it looks like we missed the mark this time. We hope he gives us another chance to prove we're the best in the business.

LOVE this cheap little module! Make sure you buy the cable so that you can flash it using the app on your PC (thank god they ditched the IE webapp) Wiring and flashing of the module overall was a breeze and only had to make 3 solder connections, in some cases you may not even have to make any at all apart from the hood latch. The range is hooked into your OEM remote so id suggest you'd get their RF kit for alot better range.

Frustrating experience

I returned this product due to fact that I tried everything possible to get the weblink updater to work with my browser. I was using MS edge and the error kept saying out of date I even disabled edge and activated explorer 11 still nothing. Instructions were very vague. When I contacted Crutchfield reply indicated error very unusual but certainly I can't be only one with edge. I would have certainly used the product had they been able to resolve. I would continue to purchase from them again but the product definitely needs better clarity.

Pros: Couldnt install so know of none

Cons: Lousy instructions.

Start to finish, would recommend. Navigating the website for vehicle specific products was easy. I called to verify my selection. Great customer service. Gave me confirmation on correct product and options. Shipping was quick and nicely packed. Installation went as expected. Guides and Tech support are available.

Pros: Using the factory key fob. Mostly plug n play. Small amount of hardware to conceal. Pleasant customer service

Product works great, easy to install with the t-harness my advisor recommended. Only issue was getting programmed, needed updated windows and a specific internet explorer edition-which isn't a crutchfield issue-they were great.

We're here to help

For free personalized advice, call 1-888-291-8923. Our Advisors have listened to most of the speakers we carry, and can help you make the best choice for your system.

We'd love to know what you think

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
