I had planned on getting an Ipad anyway so just this app was not my reason for purchasing an Ipad.
It would be a ideal solution for me instead of destroying my car again with running cables and other things. So just this app is not the reason I am buying it, It is a better solution for me I don't feel like trying to get this to work with that and so on with other equipment. I can get a base Ipad for $499 and it will work out of the box I dont have to move my seats or none of that other mess like I did with my first install.
Bottom line is the Ipad is a easy install for me to do I won't have to buy a bunch of equipment and hope it all works together the Ipad is already working.
