ymm Posted March 26, 2008 Report Share Posted March 26, 2008 My AVIC Z1 with wire bypass updated to Z2 via software is still in the 3D Hybrid mode. I have close to 5800 miles on it, bars are showing that it is almost done... but it has been like that forever. VSS is connected and counting pulses. Why would it take so long?

inferno999 Posted March 26, 2008 Report Share Posted March 26, 2008 It just does. Quote Link to post Share on other sites
cntrylvr79 Posted March 27, 2008 Report Share Posted March 27, 2008 3d hybrid is it. It doesn't go into any other mode. Quote Link to post Share on other sites
b1n2fra Posted April 16, 2008 Report Share Posted April 16, 2008 what is 3d hybrid mine says simple hybrid . whats the diference. Is it better Quote Link to post Share on other sites
inferno999 Posted April 16, 2008 Report Share Posted April 16, 2008 Simple hybrid = no VSS connected 3D hybrid = VSS connected In my experience it doesn't really matter, but for some, in some areas, it helps to have the VSS connected. Quote Link to post Share on other sites
openendstraight Posted April 16, 2008 Report Share Posted April 16, 2008 Mine says simple hybrid so I guess the VSS wire is not connected. I am missing out on anything important? I guess my question is, will I gain anything by haveing it hooked up? In my experience it doesn't really matter, but for some, in some areas, it helps to have the VSS connected . If it will not effect anything I will leave it alone. Quote Link to post Share on other sites
inferno999 Posted April 16, 2008 Report Share Posted April 16, 2008 3D hybrid means it tracks you WITH 3 dimensions, not IN 3 dimensions. The GPS antenna alone is enough to determine your 3rd spacial dimension (altitude) but as it's a navigation unit, it's unnecessary and the feature is not included. What is meant by three 3 dimension hybrid tracking is your position is tracked in 3 ways: GPS antenna, accelerometers, and distance tracking with VSS. If you're in Simple Hybrid, it just uses GPS antenna and accelerometers -- and like I've said before, this works fine for most people. It's only really necessary to use VSS if you're consistently off or not getting good GPS signal. So don't worry about it if it's otherwise working fine. Quote Link to post Share on other sites

Or if you're not happy with the smoothness of the mapscreen updates... The mapscreen is updated much more smoothly if you have the Vss connected, as the screenupdates are much more frequent as with the GPS alone... Also turnoff instructions work better/more timely, also due to the more frequent updates... Quote Link to post Share on other sites
inferno999 Posted April 16, 2008 Report Share Posted April 16, 2008 The mapscreen is updated much more smoothly if you have the Vss connected, as the screenupdates are much more frequent as with the GPS alone... Normally I'd just hold my tongue, but I don't want false information to spread. In my experience (having had both the VSS connected and the VSS not connected) the update speed is the same. The accelerometers determine whether or not you're accelerating, slowing, or cursing at the same speed even without the VSS. Off the top of my head, I'd say it updates 2 times a second regardless of VSS connected or not. Quote Link to post Share on other sites

(not wanting false information to spread ) edit: just checked the service manual, and the update rate for the GPS is once per second... Quote Link to post Share on other sites

(not wanting false information to spread ) You're missing my point. The SCREEN is only updated a couple times a second -- that's the fastest the AVIC can process. So it doesn't matter if the VSS is connected in that sense. And since it works fine for me (doesn't miss turns etc) I don't need VSS. Others may if they're not getting as good a signal or if their "learning status" is not complete. edit: Look, I'm not trying to pick a fight, and I know that everyone with VSS connected thinks they're better off than everyone without it connected. I just want it clear for teh record. I've had it both ways, in more than one car, and in my personal, imperial experience, it makes NO difference once calibration is complete. The accelerometers/gyroscopic sensors do a fine job and I get great signal. Quote Link to post Share on other sites
bridge4d Posted April 17, 2008 Report Share Posted April 17, 2008 ...or cursing at the same speed even without the VSS. Was that on purpose or a Freudian slip? Quote Link to post Share on other sites
mike@thepowdercoater.com Posted August 12, 2008 Report Share Posted August 12, 2008 I had my Z1 for 2 years before just replacing it with a Z3. They are supposed to learn your driving habits, but I went the same way to work every week and it never learned anything. Quote Link to post Share on other sites
klaborde Posted August 17, 2008 Report Share Posted August 17, 2008 I have two Z2's. I think it depends on where you live? One using 3D-Hybrid, and the other using Simple Hybrid. When I drive the hills in the Atlanta, GA area... It makes a big difference. The vehicle with the 3D-Hybrid is always right on, and the pointer stays right on the highway, regardless of Overpass's, Tunnels, etc... In Simple Hybrid, you can loose your tracking for an instance or when you make a turn, or go down into a hole. Based on my experience, you are far better off with having the VSS connection if you can. 3D hybrid means it tracks you WITH 3 dimensions, not IN 3 dimensions. The GPS antenna alone is enough to determine your 3rd spacial dimension (altitude) but as it's a navigation unit, it's unnecessary and the feature is not included. What is meant by three 3 dimension hybrid tracking is your position is tracked in 3 ways: GPS antenna, accelerometers, and distance tracking with VSS.
