This man here is the wiring GURU...
LIsten to him!
But to anwser.. yes, if you lose signal for a good while... say an hour or so, your nav will theoretically be off by how many ever miles yoru gauges are.. but the chances that you lose GPS signal for an hour or 60miles (given the traveled speed is 60mph at a constant.) are slim to none. it basically backs up the GPS just incase.
If for some reason you do get off from the nav using the vss as soon as you recieve gps signals you should be right back on track.
And KC im dying for pics of the newer ddx reciever you got! Email me a few pics of the user interface where you can add your own backgrounds. I sooo wanna upgrade the 6019. (too bad i have other things to "spend" money on) custom BG pics would rule!
Also you will recieve a PM from me shortly, hope you dont mind the questions.
