I ordered a plug and play remote start from Amazon for my 2015 Terrain SLE ($109.00), it was very easy to install, about 25 mins. I got stumped for a bit because everything I read said you would hit the lock button three times on your factory key fob, and it would start. I accidentally figured out mine will only start if I HOLD the lock button for three seconds. Other than that, it was fast, and easy. I had to splice 1 wire with the included splice tap at the odb port, everything else was literally plugs. The kit came with everything needed. If I ever have to remove the remote start, you would never know one had been installed. The listing says 2010-2014, but I verified with them it would also work on the 2015.
