Well they didnt let me touch the unit...bastards...but the interface and software is like the F900 or should i say the new X910 they have new easy to use menu system....where u can drag and drop icons to your quick pick menu...which is kinda like the most recently used sources...for example IPOD, USB, CD, NAVIGATE, HOME, ADDRESS book....and so forth...you can move the icons around on the main menu....kinda hard to explain...there should be a video out for it next week showing how this function works....and then they got the bluetooth builtin with echo cancelling....and i forget the rest...
