I recently bought a 2018 Optima and am new to Kia's. My Optima did not come with remote start and I am looking into having one installed that works with the factory key fob (not push start/stop) I have read a lot of posts about various remote start systems and came across the Omega Excalibur RS-170-B 70 Series Expandable Add on Remote Start Module. My understanding is that this works with the Factory Key Fob and I was wondering if anyone had installed this on their Optima or might have any first hand knowledge about it? Is this all that is needed for the remote start function? Just tying to figure out if I should purchase this and have a professional install it. Or if there is more I would have to purchase with this.
