garrettoomey Posted June 17, 2009 Report Share Posted June 17, 2009 The VSS is not 100 required, but it certainly helps the accuracy of the GPS. When you do not have satelites 'locked' such as going through tunnels or when you first boot up the headunit. It works in conjunction with the internal gyro. Quote Link to post Share on other sites
bloodninja Posted June 17, 2009 Report Share Posted June 17, 2009 [quote name="mwilcher"]Is this wire necessary for operation, if so why, what is it's purpose? Thank You, Matt[/quote] Read previous posts. There are like 20 pages of previous posts, and this exact question is answered on virtually every page. It's so that if you lose GPS signal for whatever reason (such as a tunnel or whatnot), it still generally knows how far you've travelled based on your vehicle's speed.

vigman Posted August 10, 2009 Report Share Posted August 10, 2009 I'm going MAD trying to find the right wire... AVIC N-3 Here what I THINK I know...... I have a question: Is pin 53 on the Nissan 300ZX ECU the VSS hookup for the AVIC?.. Need to VERIFY the VSS ( speed sence line ) so the AVIC knows how fast I'm going.. I BELIEVE it's ECU pin 53 ( Yellow / Green ) But I'm not 100% sure... Here's the spec: Japanese standard 637turns/1km 637rpm on 60km/h driving Here a difference in the VSS senders 4 Magnets : Toyota,Honda, etc 2 Magnets : Nissan 4 Magnets (4 Pulse Car) : 39.25 cm/pulse 2 Magnets (2 Pulse Car) : 78.50 cm/pulse So I will either need a shout from another AVIC owner... Or just live dangerously and try it ( Maybe hook a freq counter up first ). Thanks MIke Quote Link to post Share on other sites
vigman Posted August 15, 2009 Report Share Posted August 15, 2009 I was correct I'm going MAD trying to find the right wire... AVIC N-3 Here what I THINK I know...... I have a question: Is pin 53 on the Nissan 300ZX ECU the VSS hookup for the AVIC?.. Need to VERIFY the VSS ( speed sence line ) so the AVIC knows how fast I'm going.. I BELIEVE it's ECU pin 53 ( Yellow / Green ) CAUTION... There is more than 1 Yellow / Green in the ECU harness.. so you best remove it and count the pins... Opposite side from where the wires feed into the edge connector..Top 60 Black 59 White 58 white/black 57 green /red 56 yellow / red 55 white 54 gray / red 53 YELLOW / GREEN ( your home free! ) bout 2.5 vac 19 hz ish @ 25mph.
