I have a broken Stiletto 2 and I am trying to decide which way to go. Is the power cord adapter the same as the Stiletto 2 as the XMp3i? I can imagine the docks aren't compatible, but I'd hate to have to have my car rewired again. I was hoping to be able to mount the XMP3i dock to the same mount and possibly plug the antennas and power cords right back in without taking my dashboard apart. Thanks!
