I want to tap into teh 12volt power supply from the cigarrette lighter in the ashtray. This is for a "permanent" portable GPS receiver installation. How do I remove teh astray to get to the wires or what is the easiest way.

The reason way the cigarrette light looks attractive solution, is that I can hide the power adaptor inside the ashtray when not using it.

Any other easy ways to tap into 12 volt power.

The car is a 1999 C280
