When it’s not plugged into a GPS, make sure that the cigarette adapter isn’t plugged in, as that
makes the pins of the GPS connector live. If those live pins come into contact with metallic
objects, they could cause sparks, damage, and possibly a fire.
If you use a wire or needle to hold the pins in place while you assemble the power cord, it’s
particularly important to remember to remove it before use, as damage could occur.

If you have more than one GPS unit and their acceptable voltage ranges are different, remember
to carefully label which power cord goes with which GPS receiver. Carelessness to details
here could cause significant damage to a GPS.
The best way to avoid confusion is to label the cables carefully, as shown in Figure 2-23, and
keep the appropriate cable with the appropriate GPS. Remember to always double-check
before using.
