Hi, Paul. Nice thought. You should try to have more than one a day. I had a Drone DR2000 system installed in my RX after Lexus removed their system. And, yes it works with my iPhone. It does everything except keep the engine running. Now if someone -- I'm talking to you Lexus --can come with a fix so I can lock my doors, start my engine, know where my car is at all times, and have the engine continue to run while I open the door, enter and push the start/stop button. It can't be that difficult. Most American-made cars have them. My daughter and her husband both have Dodge cars and they have remote start on their key fob which works just like I wish Lexus would. I recently saw something on Lexus Drivers web site about a new Lexus remote system called Res+. It is $799 and works with your smart phone. Although they don't indicate that the engine will remain running after you open the doors. I asked my local Lexus dealer to research this system and if it works like I want, I will have the Drone system removed and have Lexus have another chance. I, like you, love Lexus. Their customer support is first rate and I have never had a major problem with any of the 8 Lexus cars I have owned. Paul, have a great day and if you stubble upon another idea, shoot it my way.
