Ladies and gentlemen: start your engines

iDatalink makes it easier than ever to add remote start. Their iDatastart CMHCHXA0 remote start system gives you the luxury of being able to start and warm up (or cool down) your vehicle before you begin your trip or commute. You start your car by pressing the lock button on your factory key three times. You can start your car from as far away as the key will lock and unlock your doors. 

Note: This feature works on most vehicles, but in certain select vehicles, the factory key won't work with this remote start and an RF kit will be required for installation. Please contact us for more details.

Optional RF remotes increase the range and functionality

Want to be able to start your car from inside your home or office? You can extend your remote start range to up to 3000 feet, over a half mile, with one of these RF remote kits.

Each kit contains two remote controls, an antenna module, and connection harness. The 2-way remotes feature LED and chimes to inform you what your vehicle's doing. The 5-button kits let you integrate more fully with your factory security system, letting you remotely lock and unlock the doors, pop open the trunk, honk the horn, flash some lights, and perform other functions in addition to starting your engine.

Vehicle-specific application

The iDatastart module requires a vehicle-specific T-harness, sold separately, to make a fast and fully integrated connection with your vehicle's computer, security, and ignition systems. In addition, you'll need to go to iDatalink.com to flash your iDatastart module so that its firmware will match your vehicle exactly and all functions will operate as intended. We include a USB cable in the package to ensure a proper connection to your computer.

Note: At the present time, you must use a Windows PC running Internet Explorer in order flash your iDatastart module.

We ask that you call to order this iDatastart module, so that we can offer you the correct vehicle-specific T-harness that you will need for your installation.

IMPORTANT:
If you know how to use a multimeter and have experience working with your vehicle's electrical system, you should be able to install this remote start system yourself. If not, please consider having your system professionally installed.

To ensure vehicle compatibility, please enter your vehicle information. Your order will be reviewed by our Car Experts group, who will contact you if further information or recommended accessories are needed.

It Works

Thomas from Silver Spring, MD on 6/3/2019

2003 Honda Accord EX

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was able to finally get remote start up and running in my 2003 Honda Accord EX-L V6 Coupe. I was debating for a while to either do it myself or pay an installer but when I came across the vehicle specific T-harness, I decided to give it a try. I used the OEM key fob as the main remote, maybe later I will upgrade to an aftermarket fob. Flashing the module is a bit annoying but not hard. There were about six wires to splice in total. Crutchfield's Tech support was able to narrow down the locations for the OEM hood sensor and horn wire which saved me a bunch of time. They also gave me the wiring diagram for my vehicle. The hardest part was putting the steering wheel panel back together. Honestly, this was an easy install.

Pros: Easy to install It works

Cons: No aftermarket fob included

Works, but be ready to figure out some things!

Crutchfield customer from Thaxton, VA on 5/14/2019

2014 Chevrolet Express

Verified customer (What's this?)
Verified employee purchase (What's this?)

I really like this product. Note that this product does not include remotes nor an antenna, those are a separate kit(uses a factory remote). For my Chevy Express, using the T harness(separate purchase), it was a plug and play install. What you won't find in the package are instructions. You will need a PC with a USB to wide microUSB adapter-several generations of cell phone ago(this NEEDS TO BE PROVIDED WITH THE KIT). Once you have the module connected to your PC and on the website, then programming is a snap. Not really sure this product is for your average individual, but I did get it installed and working with some frustration. Ohh, forgot to mention Crutchfield's gurus are very specific for this item, so good luck talking to one of them right away-took two days for them to call me back-I had it installed and working by then! And if I didn't mention, it works.

Pros: Plug and play

Cons: USB connection needs to come with kit. This particular USB cable is probably not in most homes anymore. Instructions are SPARSE at best. Call back from support took two days-I had it figured out by then.

...finally! remote start for my honda civic

michael from FLANDERS, NJ on 4/7/2019

2008 Honda Civic EX

Verified customer (What's this?)
Verified employee purchase (What's this?)

The winters in the northeast are really brutal lately. Decided to start looking for a remote start for my Honda Civic. After reading a review in the last Crutchfield magazine I decided to call. Calvin helped me out with the necessary products. I left them in a shopping cart for a couple of weeks. Finally took the plunge and ordered the CMHCXA0, and the T-harness for my car to make life easier... They came within 2 days. The only problem.... I have an iMac. The CMHCXA0 needs to be hooked up to a PC in order to be programmed for my specific vehicle. I was about to purchase a copy of Windows 10 and install it via bootcamp on my computer but our friends happen to have a PC sitting around. Figured give it a shot, I hooked up the unit to the PC and downloaded the software. When trying to flash the unit I kept getting a USB error. After speaking with idatastart the other day it turns out there is an additional piece of software you need to download from their site in order for the PC to pick up the unit. Flashing was easy at this point, figuring out what options to turn on took most of my saturday afternoon. Plug the box in, start from scratch, again and again. After a few hours... EUREKA! the car started! Just had to figure out how to keep the wiring behind the steering wheel column. I decided not to install the hood pin at this time. It took a week and a half with my busy schedule to get to this point. Buyers beware, do your homework!

Pros: price, features

Cons: Wish the instructions had photos of the specific plugs you need to disconnect and attach to a T-Harness

Great remote starter. A real headache due to poor instructions.

Crutchfield customer from Shinnston, WV on 3/9/2019

2007 Ford Fusion

Verified customer (What's this?)
Verified employee purchase (What's this?)

Where to begin? This starter once installed is great. It performs just as advertised. I rarely review purchases, but this one needs it. In my 2007 Fusion this was NOT "plug n play". A Crutchfield advisor phoned after I placed my order and let me know this. I still had no idea what was coming. Even using wire taps, the seven or so taps I had to make were very difficult. Car builders don't include slack in the OEM wiring for good reason. This makes standing on your head under the dash, trying to install taps a very uncomfortable experience. If your vehicle requires multiple taps and you are not experienced with car electronics and wiring, this install is best left to a professional. I've been doing my own installs for over 25 years and it was still difficult. The instructions are almost laughable. If you aren't familiar with wiring diagrams you will be totally lost. The IDatalink website for flashing the module is also not user friendly. When programming my module I didn't get the initial "green led". I was ready to give up. Thanks to another reviewer with the same problem, I proceeded through the 16 or so steps and got lucky and my programming was a success. All in all, I love the system. It could just be so much better with adequate instructions. To sum it up: Yes is is a Do-able DIY install. However, you need lots of patience and a fair amount of knowledge concerning car wiring and diagrams. Thx to the reviewer who listed step by step his install.

Pros: Works great as advertised.

Cons: Lack of instructions. Lack of instructions. Lack of instructions.

Not an easy install as is purported by salespeople.

Rich from Evansville, IN on 2/19/2019

2016 Nissan Rogue

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is in NO WAY an easy install. There are no instructions available on Crutchfield. Neither are there any instructions available on the iDataStart/iDataLink website. When I called iDataStart/iDataLink to get instructions, they said that the product is for professional installers. So...yeah. Not sure why Crutchfield sells this if that is the case. Crutchfield needs to do one of three things with this product line: 1. Provide a set of specific instructions, like they do for their car audio products, for this line of products, 2. Indicate that this product is intended for professional installers, as is recommended by the manufacturer, and/or 3. Stop selling it/them.

Pros: Never got to use it - so, I don't know

Cons: Not easy to install No installation instructions available from Crutchfield, the manufacturer, or in the box. Manufacturer says it is for professional installers

Crutchfield response on 2/20/2019
We're sorry Rich had issues with his installation. He contacted our Customer Support team and set up a return. Purchases from Crutchfield can be returned or exchanged within 60 days.

Disappointed!!!

Crutchfield customer from Norristown, PA on 1/31/2019

2012 Chevrolet Captiva Sport

Verified customer (What's this?)
Verified employee purchase (What's this?)

After spending over an hour with manufacturers tech support, I come to find out that plug and play is not the same for domestic vehicles, American vs Canadian. They differ and domestic cars require all connectors to be cut off and spliced into the factory harness. Not exactly plug and play. Programming is also an issue because the necessary information is not supplied and can not be shared with end user, notes had to be hand written to enable features. I have yet to install because of the cold here. It's not beyond my capabilities, I just wanted to not have to hack into a factory harness.

Pros: Harness looks well made, even if I have to cut connectors off.

Cons:

2016 Ford F-150 XL

Verified customer (What's this?)
Verified employee purchase (What's this?)

I have a stripper version XL work pickup. While I like it, I did want autostart. I bought the control module and T harnesses from Crutchfield and of course the service was perfect! This is a SUPER STOOPID install, and I'm still intimidated by the wires of the new cars. You create an account to get the firmware to flash your module, then install it. No wire clipping on the F150 with the T harnesses. I did not like the horn chirp on the 2nd and 3rd lock press and called customer support about that. It didn't fix it..then it dawned on me, the horn chirped when you press the lock button more than once from the factory...easy fix!! When you log in and flash the module there are a couple pages (3?) of choices and one of them is to change the default "lock lock lock" press to start to "lock unlock lock". No horn chirp now.easy! 15 minute install. Seriousy. Plug into the OBD connector and plug into the light connector, program the key with the easy instructions.BAM!!

Pros: easy, small, affordable, great customer service from CF, (of course!!)

Cons: none, zero, nada, buy it now.

Joel from Eden Valley, MN on 1/27/2019

2003 Honda CRV EX

Verified customer (What's this?)
Verified employee purchase (What's this?)

This remote start is easy to program and reasonably easy to install with the separate T adapter harness. My main suggestion is to go to get registered and use the idatastart support site for installation help. If needed you can also call the idatastart help line and get answers. If you aren't handy with a soldering iron for the few wire connections not completed with the T adapter harness, I recommend using Posi-Taps for simple and clean wire connections.

Pros: Works well and easy to program with mini USB cable after registering on the support site. Minimal wires to connect when using the separate T adapter harness.

Cons: No printed directions included in the package, so you either need a computer or smart phone handy to reference the information when installing and programming.

Excellent and Easy

2008 GMC Sierra Denali

Verified employee purchase (What's this?)

Excellent purchase. With the T harness installation was literally plug and play on a 2008 GMC Sierra Denali 1500. No hard wire connections were necessary. If your installing a telematics unit like the CodeAlarm or Viper,for sending commands with a cellphone read those instructions before flashing this module. I saw some reviews dogging on the instructions but these units are meant for installers that already know. When you flash the module there are some additional direction sheets to print off from iData and there is always the best customer service and tech support I've ever experienced if you need to give Crutchfield a call.

Pros: Simple install Reasonable price

Cons:

Product works well fairly straight foreword on how to configure. That said, the installation instructions are not all that clear especially the module programming of the keys. Mine never had a green light, however, I go lucky and it programmed.

Cons: Instruction are not clear.

Works well, instructions lacking.

Thomas from Portsmouth, VA on 12/13/2018

2017 Mazda CX-5

Verified customer (What's this?)
Verified employee purchase (What's this?)

Works well, wish there was a way to use a different set of button pushes to start. When I hit lock three times, the second and third push make the horn honk and I know my neighbors don't want to hear me starting my car at 5:00 in the morning. Also their meaning of hitting the lock three times rapidly is way different than mine. I first thought it wasn't working, but when I slowed down the pushes it started up. I would define it as pushing the lock button three times in a row slowly, not rapidly. Instructions were weak and if you don't have a lot of experience installing car stereos and accessories, it could be daunting, good thing Crutchfield is there to assist. Also I would not recommend buying this without the T-harness. The T-harness takes care of about fifty plus wires that you would have to splice down to just four. If it wasn't for the lack of instructions on how to take apart things in my car, the install could be done in thirty minutes to an hour. Another shortfall is that they require you to use internet explorer to flash and program the firmware. I haven't used IE in years!

Pros: Works well, easy to hook up if you have the T-harness

Cons: Lack of instructions

Great product so far, instructions were minimal but effective. Using the vehicle specific harness saved a bunch of time on the install. Crutchfield was great as always by including a relay that was required for proper install at no extra charge! The price of the relay would have been minimal, but the point is that they found out it needed to be on the order after I placed it and just took care of it for me!

Crutchfield customer from Mason City, IA on 11/26/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is a very comprehensive module when paired with the rf RF2352AC kit and the correct t-harness which makes it a really nice system. The directions are accurate but vague and at first/second glance the pdf guide is missing a couple of pictures of the factory harness that had to be spliced into; but, the pictures for the t-harness was spot on and the harness fit perfect. Crutchfield dropped the ball by not listing out what few steps are needed to make this a seemless install. 1. When you get your package in the mail open Internet explorer and set up an account at www.idatalink.com 2. log in to that account 3. Download and install weblink. 3. Click on the orange icon "flash your module" 4. Click allow pop up at the bottom of the page 5. When prompted plug in a male a usb to male mini b cable to your computer and module 6. Choose vehicle 7. If you have the rf kit disable the factory remote 8. Add rf remote serial numbers 9. Don't mess with any options or call idatastart if you need too, they are helpful and patient 10. Select firmware and flash the module 11. Remember the pdf with missing terminal splices?? Look off to the left of the screen and it has links to pdf's and pictures of the harness in the car 12. Route, splice, hook up. 13. Program module by steps in packet for vehicle specific instructions 14. Program module for engine tachometer 15. If you messed up reflash module and try again or call for help 16. Use your remote start

Pros: Clean install. When you find the directions, they are good. Relatively simple. So far I would buy again and would recommend, I'll touch base after a year.

Cons: Lacking institutional knowledge of some of the start up steps for install. A list of steps from Crutchfield would have eliminated this headache; but, this is minor as everything was there and a little perseverance solved that problem.

Verified employee purchase (What's this?)

Installed this in my 2014.5 Camry SE and works perfectly. The wiring diagram and instructions from idatalink/idatastart was perfect. The amount of features on the idatastart is amazing and it's all configured through a web-based interface. The product did not include the micro usb cable, contrary to the description page (if you use the micro usb cable, instead of the weblink cable, you'll need specific usb drivers). Also, the wiring harness is a must, otherwise you will need to tap into many wires. Even with the wiring harness you'll need to tap two or three wires. I was disappointed Crutchfield didn't have any instructions to remove the panels in the lower dash area (I broke one tab). I assumed they would have access to factory manuals or Haynes or Alldata, instead the support specialist recommended that I search for it on youtube (this is horrible answer). But they did give me direct access to a remote start installation specialist, just in case. Again, the product and idatalink wiring diagrams are fantastic, but you'll need to research some details of the installation. I was hoping Crutchfield would have done the research for the premium price. Also, Crutchfield support called me before shipping the product to ensure I understood the installation. Crutchfield's support is always great, that's why I decided to pay the premium price. Even though I didn't need any support from Crutchfield, I knew they would be there to support me if needed.

Pros: Lots of features in remote start Easy installation Well made product Good firmware Great wiring harness addon Factory remote integration

Cons: Installation is not for novice Factory remote limitation for Toyota's - cannot unlock after remote start Must purchase optional Remote for Toyota's

For my application the instructions from the manufacturer were way off. I only needed the t harness plugs and 2 wires spliced. Had to call technical support 2-3 times and all times they were excellent.

I purchased the remote car starter for my wife, easy installation that is mostly plug and play with only a few hard wire connections needed. This starter uses your standard key fobs and is activated by pressing the lock button 3 times. I don't like a bulky keychain, so I love that I didn't not have to add another key fob. Awesome customer service and tech support as only Crutchfield delivers. I installed this last weekend, just before the first cold snap and snowflakes of the season which earned me major points with the wife!

Make sure you flash it first and then follow the directions. I had to get some support for some of the areas. I only had to attach 2 wires for the parking lights which is optional for its use. I used this with my current stock key fob and it works perfectly. I had to call tech support a few times but they were excellent in giving me the directions I needed. I did not have to use the hood switch since the 2015 Mazda CX-5 AWD automatic already comes with a stock hood switch. Very easy to install.

Pros: Tech support from crutchfield. Comes with everything you need unless you need a T-harness

Cons: Vague company directions.

It features a user-flashable immobilizer bypass module, with no key required for most cars, that can be activated with 3 presses of the lock button on most factory transmitters. Along with remote starting, the HCX control module can also retain certain factory features such as door locking/unlocking, parking light flash, and trunk or hatch release. Compatibility and available functions will vary depending upon year, make, and model of vehicle. Vehicle specific t-harnesses are available for most cars, making installation much easier by plugging directly into the vehicle's wiring system.

T-Harnesses: One of the key time saving advantages of installing the iDatastart HCX versus other remote start interfaces is the option of using a vehicle specific T-harness for installation (sold separately). These vehicle specific interface harnesses are designed to plug into the factory wiring (locations vary per vehicle), providing a much faster and easier method of interfacing the factory wiring. T-harnesses are available for most current vehicles, please check for availability.

Note: T-harnesses will take care of the bulk of required wiring, but some hardwiring into the vehicle's wiring system will still be required.

Remotes: The iDatastart HCX remote start module is designed to be activated using either the factory remote or one of iDatalink's optional one-way or two-way remote controls (sold separately).

  • Factory Remote Control: If using the factory remote control, remote starting is activated by pressing the lock button 3 times consecutively. This same series of lock button pushes can also be used to stop the engine once it's been started. All other functions on the factory key fob will perform as they have. Remote starting range will be dependent on the factory key fob range.
  • iDatastart Remote Control: iDatalink offers both 1-button and 5-button optional transmitters in either a 1-way and 2-way design (all sold separately). Both types use FM technology to achieve a maximum range of up to 3000 feet. The 1-way remotes will give a visual confirmation that a command has been sent, via an LED indicator, while the 2-way design will give a "sent" confirmation as well as a "receive" confirmation that the command was performed.
    • 1-Button Transmitter: A single short press of the 1-button transmitter's single button will lock the vehicle doors while 2 short presses will unlock. Pressing and holding for 2.5 seconds will activate the remote starting function while performing the same process twice will shut down the engine. Available 1-button transmitters include the RF1111A 1-way transmitter and the RF2312A 2-way transmitter.
    • 5-Button Transmitter: This option provides 4 main buttons, which are pre-programmed for Lock/Arm, Unlock/Disarm, Trunk/Hatch Release, engine Start/Stop, and a 5th Function button (F) on the side of the remote. Up to 30 programmable functions are available such as; Panic, Silent Lock/Unlock, Valet Mode, Ignition Lock, Passive Arming, and many others. Each of the 4 main buttons (excluding the Function button) includes it's own LED along with a single LED at the top of the remote. The top LED will light to confirm when any button is pressed and the individual function LED will light afterwards to confirm that that command was performed. Available remotes include the RF1151A 1-way transmitter and the RF2352A 2-way transmitter.

Flashing: The iDatalink HCX remote start module will need to be flashed with the appropriate firmware for the vehicle it will be installed in. After downloading the Weblink Updater 6.3 Plugin from the iDatalink's Weblink page, the next step is to register at www.idatalink.com/weblink. After registering and logging in, the Weblink page will allow you to enter the vehicle information and then proceed to flash the iDatalink module. The flashing process must be done on a PC (Mac not supported) running one of the following; Windows XP (SP2), 2000 (SP4), Vista, Windows 7, 8.1, or 10, all using Internet Explorer 7.0 or higher (64-bits). Note: A USB cable with a mini-B connector to type-A connector (2.0) will be required for flashing.

Installation Guides: Complete installation guides are provided at the Support page of iDatalink's web site, and can also be quickly accessed from a smartphone or tablet with a QR code reader. An Owner's Card is provided with the iDatastart module that includes a QR code that, once scanned, will pull up the operating instructions.

Hood Pin: An optional hood pin-switch is provided for installation if the vehicle doesn't include a factory installed one. This important safety feature allows the remote starter to shut down the engine if someone opens the hood after the engine has been remotely started.

Engine Runtime: Once the vehicle has been remotely started, with either the factory key fob or the optional long-range transmitters, the engine will run for a programmed amount of time before either being taken over with the key in the ignition or shut down after timing out. The iDatalink's default runtime is 15 minutes but can be user programmed for 3, 5, 10, 25, 30, or 35 minutes.

Smart Phone Control: The iDatastart HCX is designed to work with most smartphone integration systems such as the Viper VSM350 or VSM550 SmartStart modules (sold separately). This allows you to remotely activate the HCX remote start, lock and unlock doors, activate the trunk release, and more, using your Apple or Android smartphone or smartwatch.

Q
Has anyone installed this on a 2018 Ram 1500 or similar 4th gen RAM? Was looking at getting this for my truck but I wanted some more details on exactly how much, if any at all, wire splicing would need to be done to get this to work with my factory fob. Thanks!

If they make a wiring harness for your car, it's almost no splicing (maybe 1 or 2 wires). Otherwise you're going to splice 20 or more wires. Check idatalink website or chat with crutchfield for more info.

Hi Gary from Dayton,OH. I too have a 2015 Mazda CX5 and am thinking of purchasing the same remote start. Can you give me any tips or let me know of any pitfalls before I start? The install seems pretty easy, it's the programming that has me concerned.

I have a camry, so not sure about cx5. Installation was pretty easy, instructions were good. Most difficult part of installation was removing the lower dash panel without any schematics (you might get lucky on YouTube). Program was a breeze. If you decide to use a mini USB cable, instead of the special web link cable, you need to find the windows drivers on the idatalink website. Precreate your account on the idatalink site, they only allow professional installers but I was able to create an account using "crutchfield" on the company field. Program the module via the web interface (its wizard based), install module, then tach program, then remote program (if equipped). Enjoy.

The Programming is actually the easiest part. The website is very easy to use. Once you hook the module to the computer and do the initial flash, the rest is pretty self-explanatory. For me the part that took the longest was wiring the few connections the T harness didn't cover.Enter an answer to this question.

I did this remote start on a Toyota and it was very simple I ran into a slight issue but crutchfield was very helpful, the programming wasn't to hard, you plug it into a computer and go to the manufacturer website and put in what vehicle and options you have and it programs it before it's installed

Hi Gary, everyone seems to recommend the Fortin EVO product for our Mazda's, I'm not exactly sure why. I tried the Fortin, had nothing but problems, a Crutchfield representative suggested trying the idatastart... easiest install I've ever done, it's literally plug & play... hook it up to your computer, input your vehicle, the idatastart automatically flashes the module for your vehicle, plug it in to your car and you're good to go. I highly recommend this product.

You need to be a powe computer user IMO. Not exactly plug and play, takes some effort.
[ MATT R  Dec 21, 2018 ]

The programming was pretty easy, The biggest issue I had is that you must use a Windows PC for the programming and I have a MAC. I ended up taking the module over to my parents house and using their Windows desktop. Otherwise, the programming software takes you step by step through the process.
[ Brock  Dec 21, 2018 ]

Programming is pretty straight forward. The worse part is you have very little time during the process but it is doable.
[ steven  Dec 21, 2018 ]
A
Yeah you're right, the installation it's not bad. Also the programing its easy the only thing that I ran into was establishing communication between the module and the computer. It turn out to be the .netframe.2.0 or something If you have any issues, feel free to contact me. Also make sure you have a usb to micro usb cable.
[ Adrian  Dec 21, 2018 ]

The hardest part about programming is getting ur computer to recognize it when u plug it in your computer.. programming it is easy. It tells u step by step.. took about 3 mins to program.
