haha i just finished installing and messing with mine for the last hour and a half or so. it definitly takes a little while getting used to especially compared to my previous cheap and simple headunit. the glide touch feature is pretty cool it takes a couple mins getting used to after messing with it for a little while which is just what most people have told me too. some of the features arent too easy to change on the fly though. like its not something to be messing with driving down the road, but its expected i guess. umm other than that its a great unit and the sq is whats expected from alpine, i noticed a complete difference right away from my old headunit.
