What's the best market car head unit for the droid's sake? There are a lot of head units that have a good functionality for the iphone. But, I was hoping that there might be something that I could sync the droid's screen on the screen of a video head unit. I was thinking that Google maps would be better than the any of the garmin maps navigation. Or should I just install something like the Kenwood DNX9140 ( Kenwood - DNX9140 ) and use the in built navigation system and just use an aux in just for music and not use the droid's navigation? Money is not an issue...I'm just looking for the best possible technological option.
