Hard to get install guides but just visit the12 volt dot com
The Compustar CS920-S remote start and keyless entry system works exactly as advertised and is a great upgrade for older vehicles. The build quality of the components is solid, with thick wiring and sturdy connectors that feel durable. The remotes have a clean layout with a satisfying click and good signal range—easily reaching across a parking lot. Installation is straightforward if you’re familiar with automotive wiring, but pairing it with a bypass module makes setup smoother. Once installed, the system performs flawlessly: quick remote starts, strong response, and reliable locking every time. Perfect entry-level system for dependable cold-weather starts and added convenience.

GOOD FOR OLDER VEHICLES, PLEASE READ
This is a GREAT remote starter, super long range, easily configurable options, and great for the DIYer that is looking to put on in an older car with an easy bypass for ignition module. Do be aware though, this is NOT for newer vehicles with push button start! If you use this on a vehicle with push button start, you are either a heathen of the automotive industry or you have no idea what you're doing, either way, stop. Newer vehicles with PBS use a low current version of this that doesn't shove a 30A fused lead into a signal input meant for only a few milli-amps to flow when the button is pressed! I had a 2012 Mazda CX-9 come in with something like this installed, completely ruined the dashboard harness when the part it was wired into couldn't take it anymore. Take it from me; the insurance deductible on a 12k electrical nightmare job is NOT fun, and nor is the jacked rates for when the bills are due. However, on the 2001 Ford Escape I put this in, worked great, never any issues, and honestly, I think it's better than the rest at the price point. Highly recommended.

Great value, simple install.
Now, a Hyundai Accent is about as easy an install as exists in regards to cars built in the past decade. No immobilizer, easy to take apart, lots of info on wiring online. Few notes that will make this easier for anyone: - Look up remote start installs for your vehicle online, finding out what to tap into is half the battle. - Speaking of taps, get a nice set of T-taps on here, you'll spend 10 bucks or so, but it's a better way to do things (unless you're a soldering genius and can do so in the cramped footwell of an economy car, upside down) - To find the install guide you'll need, search for installs of the CM900 (the brain of this system) - Zip tie all of the wires you DON'T need into a neat bundle, and then mark the ones you DO need. You'll be surprised how much this simplifies the install. You'll only be using a quarter of the wires shown for a standard vehicle. - You don't technically need to install the hood switch, leaving it disconnected looks exactly the same to the module as it does with it being installed, and the hood being closed. Other than that, assuming you can correctly install a car stereo, you can install this. Not having to run any wires through the firewall makes this MUCH easier.

Needs another device that costs 70$ to configure it!!!
After installing this in my Diesel pickup I wanted to configure the fuel pump delay before ignition and now I know that you need a separate programmer (FirstTech Compustar Programming FT-OP500 Programmer - Latest Firmware Loaded https://a.co/d/fk2z11z) just to set it up. This is really disappointing and kills the value of this product. To have what I want this device will cost 140$ dollars! I would not have done this. It does have a UART port, if the device can be configured via the UART interface then I will update the review header and give 5 stars as I have no other complaints. Update: I called MyFirstTech, and spoke to a representative who stated that the device vould not be programmed via the UART port, and that these devices HAVE to be installed by an authorized dealer, they offer no support to DIY peeps, and proceeded to regurgitate some nonsensical gatekeeping jargon. Again, i am very disappointed and due to their company policy i doubt they should be allowed to sell their product here. If youre a boomer, then go to best buy and install this. If you're in the real world i suggest just buying an arduino and some relays and afterwards you'll learn something and be able to configure your own setup with your own computer.

Works as it should.

Nice system, with some caveats
Installed well. Has some good features and expandability, but I do wish alarm options could be added on. While the system does work well, the key fob buttons are constantly being pressed in my pocket even when there’s nothing else in the pocket. That’s a first for me. For that reason, the fob gets set aside anytime I’m working on the vehicle (or there’s a valet mode, which is easy to activate). Range has been an issue, even with a fresh battery in the remote. I’ve found that I can’t let my hand wrap around the fob when I’m pressing buttons because it doesn’t seem to transmit out of the antenna bump, but rather from the back left of the fob. With my hand in the way I often can’t even unlock the vehicle when I am standing within 10 feet. The factory fob has been much more reliable. It is nice to know that when I eventually have the money to spare I can upgrade to the 2-way fob, which is hopefully better. Overall I would purchase this system again, I’m just hoping the range issues get better. Today it took repeated presses when I tried to remote start the vehicle from about 30 feet away. I finally had to stick my arm out the front door and give it a couple of tries.

Super long range, relatively frustrating to install.
The range is amazing and it works well. This was installed on a 2000 tundra with no immobilizer so about as simple of an install as you could ask for. The instructions from the company aren’t super easy to find or helpful. It’s also complicated to program, such as changing it from a pre determined crank time to a rpm sense. But $60 later and I’m not getting into a cold truck.

Si necesitas una alarma esta no es una opción, necesita más accesorios que se venden por separado, no incluye un arnés que es básico para su instalación, hasta para la función de arrancar tienes que comprar otros accesorios

Surprise, as of January 2024 the 920S comes with the upgraded 1500ft 900R remotes and upgraded antenna like the 925S ! If you have wired a stereo in your car in the past then you should have no problems installing this remote start system. Most of these lower end Compustar remote starts are based on same CM900 brain, even the 4900S which costs 2x as much. There are 2 ways of getting around immobilizer in 2000 and newer cars. You either purchase $17 Greensen /Qiiyu car immobilizer 12v kit like I did and use your spare/valet key in the box (mount it somewhere accessible so you can remove the key during summer) or you visit your local radio/alarm install shop and ask 'politely' if they are willing to sell you a pre-programmed to your car Blade AL module which slides in the back of the CM900 brain unit. Technically the remote start and the immobilizer box (with spare key) are wired separately. The immobilizer box just needs 12v when ignition turns ON. That's it. I installed this in a 2008 Subaru Forester and it works great. In a Subaru you can also disable factory alarm by inserting the key, turning on ignition and opening drivers door and quickly holding the door unlock button until you hear 2 honks. This is the best remote start option on a budget (otherwise we'd be spending $500 to have one like it installed). I used to have a Compustar remote start system nearly 18 years ago in my VW which is why I trust the Compustar brand. Yes they try to make it difficult for regular DIY'ers like us and have you go to a shop but you can get around it with some patience and some googling. Good luck.

Unless you REALLY know what you are doing or are able to get the schematics you need in order to wire this to your specific vehicle, don’t bother!! This comes with no diagrams or instructions at all. Only a QR code that requires you to sign up with compustar as a licensed dealer or installer before they decide if they will, OR WON’T, send you the install info you need or give you any support. I’m sure the unit works fine once installed, but there is a reason that FB marketplace is FULL of brand new in the box remote starters for sale… people buy them here, realize there are no diagrams or support for the average person and the wiring is over their head, so they give up, and then realize that amazon or the seller won’t accept returns. Save the headache and just pay someone to supply and install one properly. Do not buy one of these expecting to install it yourself !!
