It has worked like a charm so far. My daughter can set the heat or AC to come on when she starts it from inside the house so it will be warm or cold when her and my grandson get ready to leave. It will turn off after a while but runs long enough to do the job. It was real easy to install. I thought it was going to be harder. I was done in about 15 to 30 minutes. They have really good videos about it on YouTube because I really didn’t understand the instructions. Other than that no problem.

This product meet all of my emptions, this device is made very well and works like a charm. I called the support team before buying their product to ask some question about how the programming work and about an installation, this team was very responsive and know their product and that is why I bought it. Once I did the install that went very well and no issues, I started my car with the remote that came with it when I purchased it. The only thing that I was not able to figure out was how to keep it started once I enter the car, it would shut off. I call the support team and they said that I would need to step on the break for three seconds and it would not shut off. I replied with it should have been in the instructions. The tech replied it should have been printed on the back of the instructions, I told him I read all of the instruction and it was not there. He said did you look at the last page on the back. I reply no. When I did in was printed on the back page. All Good. The tech reply no worries, and asked if all was good. I reply with I more then good at this point.

Everything fit perfectly and the installation was easier than the videos. Programming the key fob went flawless and was fairly quick and easy.. great range, really glad I purchased this one and saved hundreds of dollars. Thanks for making a great product at such a good price.

I’m not very mechanically inclined and I managed to install it! Very simple install!

The install took me about a half hour (most of that time was zip tying the harness up to hide it) thanks to a couple really good YouTube videos. When it came time to program the unit, I couldn't believe how fast and simple the procedure was. The only thing I don't like is that when I hit the lock button on the remote 3 times, my car honks twice. I don't think that's a fault of the Start-x product but it would be nice to not have that happen so my neighbors won't get pissed at me every morning. I'll research that a bit more. Anyways, everything works as it should and starts right up. Be sure to disconnect the negative on the battery first and then BEFORE you hook up the little computer box, but only after you have hooked up the harness underneath the steering colum , should u reconnect the car battery. Nice job to whoever developed this thing. Really well made and does the job instantly. Thanks for that. Side note: why is the Mazda CX-5 the MOST expensive Start-X kit of all of the other makes and models?? That part sucked.

Install in no time. Works great. And great quality. Been using it regularly for over 2 years now.

Why did you pick this product vs others?: Al the reviews said this works great and was easy to install. All you need is a 10mm ratchet, #1 Phillips screwdriver and a pair of scissors or pocket knife to cut the excess off the wire ties

Updated review: My first unit worked for approx. 1 day. It then began shutting the car down after several seconds. It would continue to try and restart 3 times, but always left the doors unlocked. I contacted their support via Email (No support on weekends). I was sent a replacement unit very quickly. The sad part is that after installing my new module, there was a new issue. Yes, the starter started the car perfectly this time, but now it was disabling my remote key fob, and the door button used to open the locks. I was unable to gain entry into the car while it was running. I had to use the "emergency" manual key to gain entry. Upon opening the door, the car shut off instantly. There was no 30sec time-out to get in and hit the breaks. I tried reprogramming the module using the reset function to no avail. I ended up returning the unit back to Amazon for a full refund. No residual issues are present in my car, so the only thing lost is some time. No hard feeling towards Start-X. I am happy with the support they provided. It was probably just bad luck on my part. I might consider trying them again, but not sure yet. -------------------------------------------------------------------------------------------------------------------------- The only instructions are a card indicating you need to watch a YouTube video for the physical installation. Though it does help, having an actual instruction booklet would be better as you are upside-down under your dash. Second, there is never a time in the video, or on the card when it tells you it is now safe to reconnect the battery. It goes from watch the video, to push the start button twice. It is also vague on if you should actual try and start the car with the breaks on or not (the answer turned out to be no break pedal). The video does not provide any information on how to secure the box under the dash, nor does it give any cable routing information. The harness is also about a foot too long. There is no reason for this huge cable when you only need it to be a 6 or 8 inches in length. Programming takes about 30 seconds and it did work without issue. I would have given it 5 stars if the instructions were actually in existence. The functionality is perfect. Worked on the first try. I love that it works with the manufacturers remote, and that you do NOT need to send this in for programming. Would I buy it again? YES! and I might just do that for my girlfriends Mazda 3, assuming after a month or 2 it is still working.
