We received my GPS kit and have not installed yet got questions---#1 I have components connected as the bottom pix using for a 436 hand held using the 4 pin mini micro end. Will it charge also when the scanner is on or off. or do you charge as if you didn't have gps plugged in? #2 I assuming you have to set your 436 scanner 4800bps? #3 the one cable 4 pin usb will fit a 396xt, is this kit compatible with a 396xt?
