What is totally absurd these days is that they have to make a phone call to get the data, and that you can get only one at once.
They should team up with a cellphone carrier like Garmin does, my Garmin is fabulous, I can Google search directly from the unit anywhere and get instan results, and if I send something from google maps, it gets to the unit immediately. Using the phone as an old 56K modem is antiquated and slow.
Also the iPhone app for sync, a really nice concept and super fast to find places, but having to call services to get the places and go through that slow and awkward menu to get to the favorites, is slow... And don't even mention the pain it is if you English is less than perfect.
