MAKE Flickr photo pool member Ocellnuri has a clever iPod dock for his ash tray – “Slide the ash tray out, stick the iPod in, then slide it back until the unit is locked in place. This thing won’t budge. It will also fit all models with dock connectors since you can adjust how far the ash tray is slid out. When I park, I can grab the iPod out of the tray and slide it into the dash. You would never know it’s there. I had a cluster of blue LEDs made for a computer case laying around, so I wired them into a cigarette lighter plug and fixed them in the ash tray right at the base of the iPod. The light bleeds throughout the Agent18 case, outlining the clickwheel perfectly.” – Link.
