So I have my Avic D3 installed and the VSS is hooked and appears to be working.

Inside the 3D calibration screen however while the speed, right, left bars are just about full but the 3D bar is still at zero. What gives? The manual is less than through on this section of the unit.

Is this because I don't have the reverse lead connected (I don't have a camera)

I have been watching this thread for a couple days, hoping you would get a answer. I have the same issue. The only difference is I have the backup camera and it works fine. So Im pretty positive its not your reverse lead. If you ever figure it out let me know.

The only real reason that screen is there (I guess) is for installers like myself to perform diagnostics on the install without having to carry a bunch of test equipment on a test drive for a malfuncioning unit. I can tell from there if the VSS is good, and the install solid.

The 3D section is for the internal gyroscope, and will only really move if the vehicle is stopped and the AVIC is moved (like taking it out of the dash).

So to not see any activity there should be fine. The only reason I would begin to worry about anything on that screen is if you begin having problems with the nav not tracking you or telling you you are in Siberia.

Many Bothans died to bring us this information.

Yeah, I'd say if the navigation is accurate, I wouldn't even bother worrying about it.

What does it say next to "Learning Status". If it's "2D Hybrid", then your VSS is not connected correctly.

The 3D bar measures the changes in altitude. It took almost 2000 miles for mine to fill completly. A few trips to the mountains and the beach.

Simple hybrid is what my status is.

I posted because I am indeed having nav issues. I am not sure if it's a programming issue, but I often find that the GPS is behind, so if I am past and intersection, it's saying I am just entering.

It causes problems when it says turn here but I am at the intersection or passing through it.

My GPS signal say it's ok usually 1 bar and lots of yellow and orange and very rarely a green sat.

I had a much better experience with my Garmin street pilot, I am starting to think either, I haven't hooked up something right or it's just not as good.

My speed pulse is incrementing is that correct?

I am really disappointed in the documentation from Pioneer regarding this part of the unit. Is there any better documentation one of you installers could send me.

The VSS speed reading is dead on from comparisons with my odb2 non driven wheel speed readings.

Sounds like you need to position the antenna to get a better signal.

yeah I just did that. I am getting 2 bars now normally, whats the maximum?

Well I found out my problem. It wasn't the GPS at all. It was the VSS hookup.

I hooked it up to my VSS high, instead of a previous cruise control sensor.

Working like a charm. I am in 3d hybrid and the speed pulses are incrementing like mad.

I have an '06 Pathfinder and my install was working fine. A while later (3 months) my check engine light came on, I took it into the dealer, they hooked up a diagnostic machine to the plug under the driver side, then cleared the light. As I was driving, I noticed that the navigation was off. Whn I entered in a destination my position on the map was about 2 blocks from the destination. The dealer argued that nothing they did could have caused this. I took it back to the installer, he took the unit (a D-2) out and check that all the connections into the wiring harness just behind the unit. He then said it was working. When I starting driving I noticed that the unit was not sensing a speed pulse and was in "simple hybrid" mode. I cleared both and also reset the unit entriely...still not working. Took it back to the installer again and he ran a wire to the guage cluster to pick up the speed pulse. Started driving and the 3D screen reflected that the unit was picking up speed but the speed pulse still registered "0" and the unit is still in simple hybrid mode. Distances are rtecorded for distance, right turn and left turn but not 3D. Installer said he may need to contact a Pioneer rep if it doesn't enter 3 D mode. Any thoughts/solutions would be appreciated as this is really getting old especially since I am not an installer.

While you are driving, check the connection status screen. Does the beep for speed pulse change with your speed?

The speed pulse remains at 0. The 3D screen is reflecting the truck's speed though

Do you hear a beep that changes frequency depending on your speed? If you don't he tapped the wrong VSS wire

The speed pulse remains at 0. The 3D screen is reflecting the truck's speed though

The 3D screen is reflection the truck's speed based on the GPS signal and internal gyros.

If the speed pulse signal isn't going up, the VSS wire isn't hooked up.

Speed Sense wire for your truck should a be a light blue wire that was part of the stock radio wiring.

Not always. Depends on the trim level. some of them there is no vss in the radio harness. You have to go to the gauge cluster to pickup vss.

Thank you all for the input. I guess I am back to the installer tommorow

Well I spent a whole day at the installer and after talking to both Nissan and Pioneer, he could not find a working vss wire in the instrument cluster. He says he previously hooked up the light blue wire in the wiring harness behind the radio which worked until I took it to teh dealer (see above). Nissan dealer faxed him a wiring diagram which indicated that the vss wires are light blue, green and yellow, and grey (I think he said grey or grey and white). This was also verbally confirmed by the service manager. It is not consistent with what I have seen on this site. The light blue didn't work and there was no green and yellow wire in the instrument cluster. I have read somewhere in this site that all you have to do is run a wire from the unit to pin 6 in the instrument cluster.....he says he did that too with no luck. At this point he is waiting for the Pioneer rep to figure it out. Of course, the nissan dealer put it all on Pioneer. I may have to start taking bids from some of you gurus to come to Jacksonville and figure this out.

If there is not blue wire in pin 6 of the gauge cluster harness. What he'll have to do is shove a wire into that pin and ziptie it to the other wires. That'll get you vss. have had to do that more than a couple times on various nissan trucks to get vss. Of course he could take the old school route and use an external vss signal generator. Though those things tend to be a bit on the expensive side.

My 3d calibration still isn't complete after nearly 2500 miles, lol.

The distance, right turn, and left turn meters were all filled up over 1500 miles ago. I guess it's just that I don't drive up and down hills enough, as the 3D meter at the bottom of the list that collects the incline data still has one bar left before it's full.

Seems like my problem is just as yours is, except I never noticed it.

How much during your daily driving do you go up or down inclines? If it's not much if at all, the 3D meter will fill up SLOOOOOOW.

Took nearly 5000 miles before mine filled completly.

My main problem that I am trying to figure out now is that my D-2 is picking up NO speed pulse when I view the hardware/connections screen. Bottom line it seems is that they need to find the right VSS wire to tap into so the unit will pick up a spped pulse and I will start registering 3D info and move from simple to 3D hybrid mode. Shouldn't Pioneer Electronics have specific and detailed install instructions by vehicle that tells the installer EXACTLY how to hook up the VSS ? Again, I am going thru this agony becuase my GPS is way off what it used to be before I took it to the dealer. And get this....although the installer has been very diligent about trying to find the problem, his boss actually told him not to spend so much time figuring out my problem. Duh ? I paid $180 for the install and shoudnt the vss wire hookup, so the unit will work as manufactured, be included ?

Yes it is the installers obligation. Did you have a bose stereo before? what trim radio was it?

Figuring out how to use a product in one of a thousand different applications is the installer's job, not pioneer's. I'd rather Pioneer spend their money researching how to make their products better, not wasting time providing info that is usually easily found somewhere else.

I just looked in the service manual... Like stated here... PIN-6 on the combination meter harness is the speed output. Tap into that and you'll be good.
