RYCO13 Posted August 17, 2007 Report Share Posted August 17, 2007 I've read a lot of guys saying that their VSS isn't hooked up or working. so my question is ... what is it? how do I tell if its hooked up and working? what does it do? thanks Quote Link to post Share on other sites
lseguy1 Posted August 17, 2007 Report Share Posted August 17, 2007 Your manual will tell you exactly what it's purpose is for. But in general, VSS allows the unit to utilize your cars speed as an additional variable to use to calculate position. VSS plus the built in GPS ensures more positioning accuracy..meaning more accuracy of your Navigation unit. If I recall from reading the manual, VSS is especially helpful in aiding positional accuracy when driving up/down elevations, since GPS can't really calculate elevations all that well. So VSS is helpful in getting more accuracy out of your unit. Quote Link to post Share on other sites
RYCO13 Posted August 18, 2007 Author Report Share Posted August 18, 2007 so how do I know if mine is hooked up? I didn't install it but I should have. I paid someone but had to redo or do stuff that either wasn't done or done wrong. Quote Link to post Share on other sites
ChristopherLCamacho Posted August 18, 2007 Report Share Posted August 18, 2007 does your vehicle dynamics work? it should show acceleration and speed and voltage, if not it should be in a setup menu with the status of the sats. and vehicle speed, which beeps with vehicle speed. should be in the manual of how to get to it.
