Im getting my friend a ipod mini for her b-day and I want to get her a hook up for her car. Which is the best way to go with that. I hear the iTrip isnt that good? Any suggestions??

Personally, I would use a line-in (if it's feasible) or a tape adapter because the FM transmitters (such as iTrip) can receive interference if you're in an area with lots of radio station (any city bigger than Huntsville, Alabama :-P). The iTrip does look a whole lot more pleasant. I know some people have velcro-ed their beltclips to the car and just put their mini in it when they are using the car.
