I’ve done a little research on the Web and it seems to me that there are two main options for broadcasting stuff on my iPod through my car radio while I am driving. The one is the Monster iCarplay Wireless and the other is the Griffin iTrip. Has anyone has experience with either (or even comparative experience) using a video iPod? Any recommendations? The advantage the iCarplay has over the iTrip is that the iCarplay charges the iPod while driving.
