A:AnswerMy car is Honda CRV 2015 and it is compatible. There is a link in bestbuy website and you can fill out info with your car model and it will tell you if your car is compatible. My appointment to install is on Novemeber 2019 so I am sure it is compatible since that’s what it says online.
A:AnswerAs in no physical key in the ignition? No.
If you’re asking for a push-button start vehicles - I assume the answer is still no, as those do a key check once remote started before you can actually drive, so the real vehicle fob needs to be in the vehicle for this.
A:AnswerWhatever your AC/Heat was on when you got out the car will come on again once you remote start the car. I’m not sure about the defrost part because I have a 2012 Accent and you have to manually turn on the defrost to work but it’s summertime currently so I haven’t had a chance to use defrost since I got this system. Hope this helps!
