I'm looking for a good iPhone 3GS car holder to use in my Fiat 500. I plug my iPhone into a USB port down here ... (not a picture of my 500) ... so a cable has to run down there. So I reckon the most 'stylish' solution would be to cradle it in a cup holder mount that's located right next to the USB port, but that would render it useless when I'll be using my iPhone as a navigation device along with the upcoming TomTom software. The USB port will power the device AND let me gain access to its music library to play through the car's stereo system ... So now I just need a convenient, stylish place to put it... suggestions? Maybe even a cradle/mount/car dock that lets you attach your own iPhone sync cable to it? (don't know if that exists, though ...) Thanks in advance!
