Did you Check the antenna too?

Yeah, signal strength is good. When driving around, it accurately shows me my position on the map no problem. (It always has.) Since it is not calibrated, though, it won't do any of the dynamic routing stuff. I can give it a destination, and it will generate a route to that destination, but once I start driving it won't give me turn-by-turn instructions, nor will it reroute if I get off track.

I'm assuming it has to be calibrated before it will start doing all the routing features. This is one of the design decisions that frustrates me the most about this unit. It shouldn't matter that the gyros and VSS wire aren't calibrated yet (or if they are not even hooked up at all). It's got a solid gps signal; that's all it needs. While it's calibrating the gyros and VSS, it should still be able to function fully as nav unit unless I lose gps signal. Pioneer decided that's not the case, though, so they make the thing useless until it has calibrated all the sensors. Neither my dashtop Garmin unit nor my Alpine in-car unit in my other car require this. They are fully functional the moment they have a good gps signal. The internal sensor calibration (gyros and VSS) all happens in the background without you ever having to worry about it.

Sorry if I came across grumpy in that last post. I'm just getting frustrated with it. Regardless, I definitely appreciate all the help and suggestions everyone has provided so far. I've just never had this much trouble with any of the many nav units I've ever owned, so I guess my tolerance is a bit low.

If that's the case, then you've got a problem with the avic. They normally start routing as soon as they're installed and picking up a gps signal.

Ah, that was actually my next question. When I *first* installed it after I bought it, it did indeed do that. I didn't have the VSS wire hooked up, but I did notice that the learning screen immediately started showing gyro learning data as soon as I started driving. After a couple of days, it gave me the "incorrect installation angle" error, and stopped learning. Ever since then, I've never been able to make it learn again. I've fixed the installation angle, hooked up the VSS wire, reset the learning data, *and* I've hit the reset button on the front of the unit after each change, just to make sure I was starting from a clean slate.

Sounds like there's definitely something wrong with the unit. That's unfortunate, since I bought it second-hand and it did seem to work when I first got it. I guess that puts the blame in my court and leaves me with an expensive door-stop. Too bad I bought the XM/NavTraffic unit for this thing. I guess I can still sell that, though, since it works great.

Any idea how much Pioneer charges for out-of-warranty repair on an AVIC?
