Nobody smokes any more, so why not use an ashtray for something ... useful?

This is an insert which fits in an Infiniti G35's ashtray (2003 and other similar models, perhaps). You can customize the SKP to add whatever you want. In my case, I've installed:

• one switch to enable my nav hack,
• one switch to turn off my CarPC,
• two USB ports.

Note: to fit the USB connectors, I had to take some significant plastic out of the innards of the ashtray.
