I looked on their website and the new head units now from Alpine have "Full Speed Made For IPod" on them. I even got to use a girls new alpine headunit last night with the Full Speed feature and it was great. Worked very fast, almost the speed of the ipod itself.
One really cool feature is the numbers 1 - 6 along the bottom of the headunit can be used as percents. For example, when you are reading the huge list of artists, 2 will put you in the E's, 3 will put you in the I's, 4 in the O's, 5 in the S's, and 6 in the W's. This is just to give you an idea of how that works. Once you learn where each number puts you in the list, you can learn to navigate through them very quickly.
