I am creating this thread as I can't find any info on forum. I have recived a Lexus Enform news letter from Lexus.
By default we get one year subscriptions to Lexus Enform and you can download mobile app for it too (iPhone, Android and BalckBerry). You can add multiple Lexus vehicles (2010 above) to share stuff like eDestination folders.
You can manage your destinations in mobile app or online and send it to your vehicle. They will display in eDestination folder.
I thought it might be useful info and I haven't explored all options.
