When I try to use the slope reading in the VDD screen, I get a message that "This function is currently unavailable". I see nothing in the manual that really tells you how to "set it up". I have only two connections left off, the VSS and reverse light, so I don't see that those should be affecting it. Everything else works great. Any ideas?

You do have to drive about 50- 100miles ithink before some things become active.

So far, I've put over 600 miles on the car since installing the N1 last week, so I don't think that's the issue. But, thanks anyway!

Problem solved. Without a speed signal, the learning status stays in "Simple Hybrid". Once I hooked up the speed signal and drove the car, it went into 3D Hybrid, and now slope works :P

You beat me to it. You need the VSS to figure out slope. If the nav knows how fast you were moving on the ground using VSS, and it knows two GPS fixes, it can calculate that there must have been a certain degree of positive or negative slope involved. At least that is what I think it might be doing.

By the way, 3D is much more accurate than Simple. I didn't have the VSS either for a few weeks, and it was way off. Now its very accurate.

I have the same problem but whats weird about it is that I see the red indicator moving and it seem to be acurate.

So is their another way to make this work? Everything else work perfectly.

How do you find the VSS wire ? I've got a 2004.5 Dodge Ram Diesel

Like this. It's dark green/yellow at the ECM on the lower driver side of the engine, 50 pin plug, pin 11.

Can someone tell me where the VSS wire is on a 2002 Expedtion

IF your stock radio had speed controlled volume, look for a gray/black wire in the radio harness. That will be your vss. Otherwise here ya go.

Speed Sense gray/black cruise control module
Notes: The cruise control module is on the driver side fender.
