i guess i'd hafta find what that wire is and where it's located on my truck and connect the two. I guess i can try plugging the old GPS antenna in and see if i still get the "excessive vibration" for the installation postition.

well after taking a drive...still nothing. I noticed tho that a few seconds after i put the vehicle in drive and take off...the installation position setting went from "OK" to "excessive vibration", then just after i come to a stop it goes back to "OK". I also noticed that when it goes to "excessive vibration" i have no satellites, but when i put it in park and shut the vehicle off i get two of them, but no more than that. I ended up pullling the whole head unit out of the dash and noticed that the "car speed signal input" wire isn't hooked up...does it need to be cause the previous owner r

VSS? only thing i diconnected was the old GPS antenna and connected the new one. I installed the new GPS antenna yesterday and then reset everything. But i didn't drive anywhere after that or start the truck...Maybe thats why. I'll go for a drive today and report back.

I did the 3D calibration resets and i now have 0 as distance and the learning status now says status initializing. Also the GPS arrow is now frozen and doesn't move at all. Here's some pics i took....

how do i go about doing the level resets and the reseting the 3D calibration?

Thanks for clearing this up. Maybe i'll wait for the 2011 update to be released. Just gotta wait for the new antenna to show up and hopefully it's better. I did notice today that there were a few times that the GPS was displaying the correct location where i was driving, but then there were times when it wasn't. The GPS antenna has been in the same spot since i installed the unit...which has been a couple months ago and never had any issues with it unitl it just started acting up a couple days ago.

thanks! Now if for some reason there's a problem with the so called gyroscope...does that mean the head unit is toast, or could it be fixed?

so it looks like it's just a CD for the avic Z3 then right? Do i just put the cd in the head unit and does it automaticly update then?

just bought an antenna off ebay for $25...hope that works. How do i update the GPS system to the most recent 2011 maping?

i'll try that. where's the best place to get a replacement antenna for it?

I bought an avic Z2 off a guy which he had updated...so he told me it's actually an avic Z3 now of the update. Since it's been installed, everything has been working great up until yesterday. The GPS has just started acting wierd. The GPS's indicator arrow is telling me that i'm nearly 5 miles away in an open field. When i start driving the arrow is no where near where i'm actually driving. Would there be something wrong with the GPS antenna?
