Gave 4 out of 5 stars, only due to the poor quality of installation guides; the electronic devices themselves are great quality. ONLY ATTEMPT to install this remote start system if you are mechanically inclined and electronics savvy, or are under the supervision of such a person. I have 20 years mechanical and automotive experience and the downloaded instructions were VERY vague and confusing at best. I took my time with this install, as electronic components in modern vehicles are very expensive to replace if damaged. I did my research, collected all the YouTube videos, the relevant forum guides for my vehicle, electric current testers, proper tools and this job took me 6 hours all said and done. BE ADVISED, you must buy the $50+ firmware flash device. The EVO ALL is mass produced and the flasher is needed to make the EVO work correctly for a specific vehicle application. The key things that really helped the most were the online .pdf guides, wire diagrams and pictures from wirecolor.com, a website also owned by Fortin.
All in all, great quality devices and pretty cool system if you can understand how to install all components specific for your vehicle. If not, buy the EVO and firmware flasher, update the EVO device yourself, (which is very easy, just requires a windows PC and an internet connection) and have a mechanic and/ or auto electronics shop install this system for you.

Bought this for my 2014 Nissan GT-R track edition. After hours of exhausting research. I've finally realized why this pos doesn't work. You have to splice into your push to start ignition switch, as well as splice in grounding wires and cut other wires. I have no interest in cutting into my cars wires so I will not be wasting money on this. Spend the extra $100 and get a real plug and play kit.

I bought this item mainly because it made use of the original remote control, I did not want my daughter to have to carry another remote.

BEFORE YOU START, YOU MUST ALSO BUY THE PROGRAMMER! I updated the EVO with the latest firmware and configured it to be used as a remote start by pressing the lock 3 times. I'm not sure why they don't just ship them like this from the factory, but mine did not come configured this way. If I did not change the configuration, then I do not think it would have worked. So buy the programmer, like others have said.

I used the following web page that clearly describes how to install it into a 2010 Nissan Altima:

[...]
Key notes include:
1) You will have to remove the instruments cluster from the dash (pretty easy) to gain access to the BCM.
2) 2 of the wires connections to the BCM are simple push in to an empty slot of the green connector.
3) 1 of the wire connections to the BCM must be made using a T-Connector or Soldered (I stripped and soldered mine)
4) 1 wire must be soldered to the Push-to-Start button
5) 1 wire must be soldered to the Fusebox connector
6) Everything else is a simple unplug-plug and requires no cutting or soldering

In general there was only about 10 screws that needed to be removed to gain access to everything which is all under the drivers dash. Once we had all the wires connected (except the brown wire to the fuse box for the parking lights) we programmed the unit using the instructions from the Fortin web site. We also watched the following video which is for a Maxima, but works the same way:

There are a few different PDFs instructions to use, but I found the following PDF was the most accurate for the installation into an 2010 Altima:

[...]

After we proved the car started as expected, we finished the job by making the connection to the fusebox for the parking lights and wire tied the lose wires and the unit to the metal support under the steering wheel (so nothing is banging around or hanging by our feet).

I'm not sure if the standard remote will reach the car from my daughters dorm room, but we can just add a Fortin RF-KIT that has an extended range (some 3500 feet).

Overall, the installation took about 2 hours, but we went slow, soldered the connections (instead of using the push-on taps), and double checked everything before cutting or stripping a wire. We are pretty experienced working around cars, so it might take a little longer if you are not, just take your time, and read the directions from the first link (many times).

This worked great on a 2012 Infiniti M37. Very easy to program and install. The only thing I wish it did, was control the door lock and unlock functions via CAN-BUS. For the M, you have to hook into the actual lock/unlock switch in the door. This means running wires in the door which is not as easy as hooking things up under the steering column.

I installed this in an Infinity EX35 in about 2 hours. 1 of those hours, however, was trying to access the plug at the back of the push-to-start switch. You must make a connection there, and there is absolutely no way of doing so without removing half of the dash board. Once I learned that the switch simply pulls out the front of the dash after popping out with a plastic non-marring pry tool of some kind, the rest of the installation was very straight forward. The quality of the components in this kit are first class, and yes you will have to purchase the Flash-Link Update tool. Also be aware that there is a several second delay before the engine starts
