Not compatible with OEM Remote Starters!!

Bought this thinking it would work in addition with my Nissan’s pre existing OEM remote starter. Confirmed it with a total tech online rep along with a call center rep over the phone that it should be.. just to get let down the day of my appointment that I would need a compustar remote starter kit in due to this product not being compatible with OEM remote starters. Frustratingly had to return and get the whole kit, (had to order additinal parts online) still have to see if they can even disable my OEM remote starter without me taking it to the dealership. And if they cant then the whole kit bundle was a waste and BestBuy in all wasted my time, money, and energy.. what a joke. Be warned about purchasing products and do additional research, sadly cannot trust their word on product compatibility
