Early in the 2010 production cycle, some Lexus had difficulties with iPod scrolling. The car would "auto select" the topmost song in a list, hesitate and start playing the topmost song of the list. When you would scroll down the list, once again the car would pick the topmost song in the list, hesitate and begin paying that song. Later in the production cycle a navigation system firmware update enabled "proper" scrolling in which the current song would continue to play while you would scroll through the list and you would pick a song, which would then start playing.

Lexus has corrected iPod scrolling for some of those vehicles manufactured early in the production cycle. If you have "defective" or "abnormal" iPod scrolling, try contacting your service advisor as an update is available for some models and vintages of Lexus with navigation.
