Snoop's Take

The Compustar CSX4900-S is a 4-Button 2-Way Remote Start System designed to enhance your vehicle's convenience and comfort. It features a 3000-foot range, allowing users to start their car remotely and includes the Drone X1-LTE for smartphone control, making it a versatile choice for modern vehicle owners.

Many appreciate its ability to provide climate control setup, especially during extreme temperatures, stating, "they are also nice to have when the temp gets to 95 and you’re parked in the sun." However, some users also caution about the need for an app for full functionality and mention installation costs being higher than expected. Overall, the Compustar CSX4900-S is highly recommended for those seeking a reliable remote start system. Despite minor drawbacks related to installation and app fees, the product’s excellent range, solid build quality, and positive user experiences make it a strong contender in the remote start market.

What it does well!

Key strengths users can’t stop talking about.
Good range for remote starting
Remote start options? Hey all! I really would like to add remote start to my 2018 Touring CX-5.
Is there an OEM fix to add it?
Is there any reason I should get #1 ($600) instead of #2 + #3 ($450)?
Allows climate control setup for warming car
they are also nice to have when the temp gets to 95 and you’re parked in the sun.
Easy to install without returning any parts
If you don't care about an app or starting your car from anywhere in the world, this is a good kit.
I didn't have to send anything back.
Solid product quality
The product is solid, but requires skilled installers too.
Low current draw when idle
The unit draws very little power while in wait.
Remote starting from anywhere with Drone Mobile
You can start your car from literally anywhere in the world.
Includes 2-way remote for feedback
If you plan on using drone mobile through your phone, you won't really need the 2 way remote.
Complete system includes necessary parts
I sell it like this to my clients to Dave em the money too.
App is superior to competitor's app
The app is miles ahead of the Mazda one.
Provides useful vehicle information
It’ll tell you the battery voltage, if any doors are open, a GPS location of the vehicle and the temperature in the car.
Fantastic range for remote starting
But compustar has remote start features but I don't know much about them beyond that...
Compustar is a great choice for remote starters
Compustar is a great choice for remote starters.

Where it needs some work!

Areas to watch—feedback on possible improvements.
Cruise control error when starting car
All in all, I really like it. It was easy to install and affordable.
Requires proximity for starting car remotely
I was hoping for something that would allow me to start my car while I’m getting ready inside the house in the mornings to warm it up.
App required for full functionality
I think it is crazy that I have a remote starter in my 2020 Outback but can only use it if I pay for the app.
Limited range with original key fob
it doesn't have that great of a range from what my sales person said.
Fob loses connection issues
I found out if the fob loses connection to the car the push to start button won’t work.
High installation costs compared to MSRP
I'm struggling to figure out how installation is over 1k.
I feel like the Midwest winters aren’t as bad as they used to be.
Signal blocked by buildings and obstacles
The minute you have any kind of interference that rated distance can drop significantly.
Anything between you and the car could (and probably will) restrict range.
It looks like the only solution is to get the drone module installed but then again why advertise 3,000 ft?
Complex installation process
I highly recommend buying one through a dealer and having them install it.
No plug and play option for some vehicles
Wow so no plug and play. Oof okay!
Subscription fee required for app usage
Starts at $5.99/month, goes up to $11.99.
Monthly fee required for smartphone features
You could always do the one you can do on your phone. Has a monthly fee though.

Questions about feature compatibility with proximity remotes.
I feel like this is a series of silly questions, but I'm asking anyways...

the manual actually is very vague about this.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Different remote options available in the market
Fortin is another one to look into.
Confusion about installation options
No way to use the app for free and no way to use the fob without the additional hardware.
Concerns about subscription models for remote start features
Get start x, don’t support auto manufacturers and their “subscription for features” sales model.
I seriously despise the idea of paying a money fee for something the car is already equipped with.
Comparison of Drone Mobile with other remote start options
I don't to pay Mazda's extension cost for remote App access.
the app based service like Drone Mobile doesn't work with it.
Discussion about installation warranties
Does Best Buy warranty their installs?
Variability in installation times based on vehicle
Depends a lot on the vehicle and some on the skill of the installer.
Considerations about installation experience and options
the whole installation which can be some what tricky.

Do you know where I can look for software updates and how to install them?
Discussion on compatibility with factory and aftermarket options
I have a Mazda key fob for the remote start and whenever I open the door or trunk the car turns off.
Need for OEM keyfob information for installation advice
Vehicle Year Make and Model is quite important to answer your question.
Discussion about keeping factory alarm while using remote start
You don't want to carry two fobs you do want to keep the factory alarm but then you ask if you should get the remote start security system or a two way with a fob.
Inquiries about other model recommendations.
I’ve been looking for the sale for a month and nothing 😭

Cautionary Callouts

I’m planning to get it installed with the impact/tilt sensor for $1130 CAD which I think is reasonable?
Discussion about fuses affecting functionality
You are a lifesaver! I really appreciate your advice!
Hope this helps.

As someone who does about 20 a week now and about 40 in the winter, go compustar. They just work!
