So i have a Garmin V handheld GPS which does the point to point navigation. Although I use it for geocaching, 90% of the time it is in the car and I'm sick of seeing the power cord hanging from it. Plus, a lot of the time I want to charge my cell phone or something like that. Is it possible to hard wire the cable to the cars electrical system? I don't know anything about currency and whatnot but shouldn't it be possible? The cord will still be showing, but only about 2 inches of it.
