    • Reliable remote start system with long range
This remote start system is a solid option if you’re looking to add remote start and keyless entry to your vehicle. The 2-way remote is a nice feature because it confirms when the vehicle has successfully started. The range is impressive and works well from a good distance, which is especially useful during colder or hotter weather when you want the car ready before getting inside. The remotes feel durable and the controls are straightforward to use. Once installed and programmed correctly, the system works reliably and responds quickly when starting the vehicle. Overall, this is a dependable remote start system with good range and useful features for everyday convenience. ... show more

    • Locks may require relays.
Used to replace a burned out bull dog system, motherboard. Installing this system was simple until the door locks portion. Prior system controlled the door locks without relays, this one not so. Vehicle installed in; 1995 dodge ram automatic 5.9 liter. Had electric door locks built in and triggered with negative current which with this unit requires two 5 pin relays. You'll be wiring two posts each to hot, one on each to vehicel existing lock and unlock wires, and to same coming from remote box. No posts go to ground. You have to test which end of the vehicles lock and unlock wire is going to the motor or coming from the switch after you cut the vehicle wires one being lock and the other unlock - you have 4 wire ends you tie into using the relay posts producing 4 wires and they need to connect to right existing lock and unlock ends and you determine the ends by using your vehicle lock switch to identify; hot = switch side, other by default is the actuator side. Then you can finish the wire connections. I went to manufacturer’s web site, training for installers and found a specific video instruction re: locks and relays-the instructor speaks the wiring pin to relay numbers arrangement. Takes notes and apply. Manufacturer sells a dual relay wiring harness or just buy two 5 pin. 4 pin won't work - 87a post is needed and 4 post doesn't provide. The rpm sensor i left in the default mode which is alternator or voltage sense instead of rpm coil sensor. Just wire sensor wire to relay hot wire source as it’s direct to battery and fused of course. As soon as it starts the rpm sensor which is intended to issue a signal back to the brains that the engine started is instead using the alternator sensor for volt signal increase. The remote will issue a confirmation tone that your vehicle didn't start so it kept the starter turning til it toasted out, caught fire and burned your vehicle to the ground....kidding of course but that could happen if there’s no signal to identify engines running, so wire that sensor, use the power relay source and fuse protect it. The burn to the ground wouldn’t happen, there’s a time out starter engagement limit so relax ladies and why are you reading this install review, he’s installing it. Lots of mod options to change attributes that you can program via remote key pad. Remote start is great, antenna pick up is great; hit the button, listen for confirmation, go back to bed for 15 or longer (programmable). If keyless is backwards as mine was it was caused by the motor wiring on one actuator is backwards. Good value, small unit, light weight, plenty of wire length, need two 5 pin relays on certain lock trigger type vehicles. Happy camper. ... show more

    • Compustar CS4900-S is an awesome remote start and keyless entry system!
This is the second unit I have bought and have installed on both my truck and Jeep. The system is very responsive and the remotes feel quality and work very well. Each system's installation was simple and straightforward, and the wiring in the instructions is very clear. I highly recommend!

    • Works great
I installed this myself. (If you are not comfortable with electronics and taking your time installing, get a professional to install this). Installation was average, lots of wires to find, check voltages, route, solder, etc. It took me about 5 hours or so taking my time and double checking my work. It was well worth the time!. I also highly recommend you connect the tach lead, and calibrate it (this will allow the system to know when your car is started by the engine revs, so it will start perfectly in all conditions). Now I have a warm car on cold mornings. or I can leave the car running, get out and lock the doors if I need to run in someplace quickly. This is my first 2 way remote, and it's a game changer. no more guessing if it actually received your remotes command. The remote itself beeps at you to let you know it did. Speaking of remotes, the range is amazing, I keep testing it thinking "no way it's going to work from here" and sure enough, it does! ... show more

    • No instructions
Do your research! This is a great product, unfortunately they don't offer details installation instructions like other brands. Compustar is a professional installation brand not designed for DIY. If you buy this you'll also need the programmer to adjust settings or have to go to an installer for these adjustments. I spent twice as long figuring out how to wire this unit into my truck as I did actually installing it. Luckily I found a good forum with an article from a guy who documented the wiring. Would have given it 5 stars if they had instructions. ... show more

    • I figured out how to program the options but don't expect Compustar to give you any help whatsoever
TLDR? Don't get a Compustar. Get a Crimestopper. Even better, get the system from MyPushCart. They provide 100000% better customer service, and their smart phone module subscription is far less expensive, and with smart phone control, who cares about the fancy features Compustar offers? The install was easy. However, their customer service is terrible, and that's what the rating is for. I wanted to change the remote start runtime but the procedure in the manual doesn't work, so I emailed Compustar. They replied that the options cannot be changed via the remote. I let them know there is a table in the manual telling you how to do it, and then they said that's for the installer and they don't want end-users to change the options because it could blow a fuse. Seriously? In the end, I figured it out after Googling. You have to follow the instructions for the 1-way remote, and you have to do it while the key is out (ignition/accessories off). Also, the subscription fee for the Omega mycar smart phone module that mypushcart sells is significantly less expensive than compustar's drone. In fact, I'm about to tear out this system from my car to install a Crimestopper unit (the brand mypushcart carries) so that I can use the mycar module. See, I'm willing to uninstall and reinstall my remote starter because of my dislike of compustar. You like their features? None of that matters when you have a smart phone module where you can start, lock/unlock your car from wherever you want. Plus, you don't have to pay double for the GPS tracking system like you have to with Drone. Compustar thinks you're too unintelligent to install. They purposely left the incorrect instructions in the manual after all these years. I suggest buying systems from mypushcart. They actually help you! And their systems come ready for your specific vehicle. Also, Omega's customer support is excellent as well. Compustar takes so long to reply that you might as well...well, I'll stop here. Don't buy a Compustar! ... show more

I contacted Compustar, and they Informed me that I should Not have been Able to Purchase, here on Amazon, and should have Purchased at a Local Dealer, and Only they can Fully Program.

    • Great customer support if needed
Have a cm6200 brain, plugged wire and antenna in to upgrade for new remotes. Originally it would only accept the 1 way. Discovered The brain needed a firmware update and now they all work. Great customer support and they really care about the customer.
