Its not all identical just when browsing through song really fast it takes it like a millisecond to show the name. Other then that it goes through them fast, I don't know if mine has a search feature cause i just pick an album and play through it for a while. When i start my truck it takes only 2 or 3 seconds to load the ipod then its ready to go. Like i said i have no experience with the alpine or pioneer so cant compare with those brands but i had a jensen that was slow as hell. The only part I dont like is when you first start searchig from the list and it starts at A and the album you want starts with S you cant you cant go inrevse to get to it you have to go through the whole alphabet to get there and when my ipods full it can take some time.
