slicknick Posted February 20, 2008 Report Share Posted February 20, 2008 When I drive down the road my arrow points to the right about 60-70 degrees. this causes my D3 to want to turn on all these streets, causeing inaccurate navigation. How do I go about "recalibrating" or whatever I need to do. I was under the assumption that it just did it itself overtime, but it's been 100 miles and still no good. thanks Quote Link to post Share on other sites
slicknick Posted February 20, 2008 Author Report Share Posted February 20, 2008 Do I have to take the unit out to reset this? can I just hit the reset and drive around. Quote Link to post Share on other sites
slicknick Posted February 20, 2008 Author Report Share Posted February 20, 2008 could it be that there is no metal plate under the antenna? Quote Link to post Share on other sites
inferno999 Posted February 20, 2008 Report Share Posted February 20, 2008 Try resetting the 3d learning and distance studies. Quote Link to post Share on other sites

inferno999 Posted February 20, 2008 Report Share Posted February 20, 2008 How do I accomplish that? "When the navigation system begins running for the first time, the 3D Hybrid Sensor automatically begins initial learning. Positioning is performed solely by GPS satellites until the 3D Hybrid Sensor initial learning is complete, so the location of your vehicle may not be very accurate. This is not an error. When the initial learning is complete, the location of your vehicle can be detected with high accuracy." To clear values: [*:pslbw7gv]Touch “Settings†in the NAVI MENU, then touch “Hardware Infoâ€.[*:pslbw7gv]Touch “3D Calibrationâ€.The 3D Calibration screen appears[*:pslbw7gv]If you want to delete the learned results stored in“Distanceâ€, “Speed Pulse†or “Learning Statusâ€,touch the relevant result, then touch “Clearâ€.

John@20Squared Posted April 22, 2008 Report Share Posted April 22, 2008 What exactly does the metal plate do for GPS accuracy? Quote Link to post Share on other sites
Julius Posted April 22, 2008 Report Share Posted April 22, 2008 It increases the reception sensitivity of the antenna.Better reception better accuracy. Quote Link to post Share on other sites
shoman94 Posted April 26, 2008 Report Share Posted April 26, 2008 All that metal plate does is allow you to stick the antenna on a non -metallic part....like the plastic dash. It doesn't effect reception. Quote Link to post Share on other sites

It doesn't effect reception. No, the plate acts as a ground plane for the antenna and does affect reception. You can use the antenna without the ground plane and sometimes you'll get decent reception anyway but you'll get better reception with it than without it. Quote Link to post Share on other sites
