Perhaps you don't have the speedometer and or speed pulse installed so it doesn't know you are moving. I noticed that when I sat there and looked at the menu items they would fade in and out as if I had been engaging and disengaging the parking brake. When it faded in, my dvd would play even moving slowly but when it faded out or my speed got to over 20 mph it would turn off. The routing always blowed. [quote name="marathonfl"]I just purchase a Z1 yesterday, installed it last night, the light switch does work when you flash the light switch at boot up before the Pioneer screen comes up

When I actually needed it it did route me incorrectly. And not because it 'learned' a bad route from me. You can't even select the proper route on I95, all the choices have at least some US1, which is totally wrong. I returned the unit earlier today and will be using with my Magellan 700 which uses a different and more reliable nav data set and superior, in my opinion, algorithms. [quote name="Anonymous"]Mchance, I read in the other thread where you were complaining about the avic always using US 1. The same thing happens to me, it seems to think that taking us 1 300 miles south to

My wife took my Porsche in today to the the Z1 uninstalled....thank goodness!! Never be a first adopter. Especially with gadgets!

I saw another rumor that someone had removed a label and discovered a switch to remove the interlocks everyone has been discussing. Sounds a little hard to believe. Plus we would all miss flicking our headlights and being lost.

Yes, here was the response: Thank you for contacting Pioneer Electronics, Inc. I am sorry to hear the problems you have experienced with the AVIC-Z1. I will forward your comments to the product planning division. I am sure your comments will be looked at closely and considered for future product changes. Thank You, Rocky Customer Service Representative Which is why I finally decided to take the unit back. [quote name="HeavenSoldier"] [quote name="MChance000"]I am returning my Z1 tomorrow. You guys can spend the rest of your lives flashing headlights if y

Actually, when I just sit and watch the menu buttons they seem to periodically enable and disable by themselves, almost as if you were putting on and off the parking break. I think this is why a lot of people on here think the light switch trick is working.

I am returning my Z1 tomorrow. You guys can spend the rest of your lives flashing headlights if you want to.

Well, I have detailed the problems profusely in a number of post in this forum and others. For example, I 95 connects cocoa, fl and daytona beach. You would think that would be the fastest route. some how the z1 thinks US 1 is the best route, even though it drops to 35 mph through titusville and on and on. In Jacksonville it took me on a 20 minute trip through downtown when a proper route was just across the way and 5 minutes. I could go on and on....but why repeat what I have written before. Go to the problems/troubleshooting section and check it out. [quote name="edrock200"] [q

Obviously I am aware a nav update won't require a hack. Just seems everyone is spending a lot of energy hacking for functionality and decisions that should be the owners. Not to mention even when the dvd is running it is second rate at best compared to other units on the market. Yeah, I did note that another Porsche owner had speedo problems. But that aside as an *additional* problem and burden we bear, doesn't have anything to do with the exceptionally poor routing these NAV units provide. I mean, the reason you buy a nav unit is for nav, right? That it is a crippled crummy nav just

Has anyone discovered a hack to update the nav data, improve nav? Once you get past the pretty screen and the unavailability of options during motion you realize the the nav itself blows. I know, I tried to depend on it.

Maybe. But I would wait a while till some other pretty face became available or they got the problems worked out on this one. Why pay to debug.

No Soundadvice (Tweeter) in Orlando. Can't wait to bring it back to them, either.

yeah, the Magellan isn't perfect I own two and have had problems with both. But, they are great at simple navigation and route better than anything. The point was a comparison, I could have pointed the results with mapquest, streets and trips and tomtom which I have all used agree with Magellan but not Z1.

You might want to reread the crutchfield reviews, the third one agrees with much of what I said here. [quote name="HeavenSoldier"]Hmmm, I'm still going to get it though, most people told me they're avic z1 navigation was dead-on accurate, check crutchfield user reviews here [url=http://www.crutchfield.com/S-LU1FlQeQwQN/cgi-bin/ProdView.asp?search=avic+z1&i=130AVICZ1]http://www.crutchfield.com/S-LU1FlQeQwQ ... =130AVICZ1[/url] , But I will find out for myself if something is wrong, but based on other reviews and forums, it's the best navigation so far. Like I said check with your install

You can get a lot of things to look good in your dash for a lot less than $3000 with install. I just used the Magellan as one example of good navigation with a little money, almost anything is better at navigation than the Z1 in my opinion. It isn't that it won't get you there (eventually) it is just that instead of a 5 minute route across the street you might get a 20 minute route. Not always, but lots of the time. And it requires a lot more effort to get a route. I just think Pioneer spend their energy, creativity and money in avoiding liability by crippling the unit when moving and no

My speed is off from anywhere between 4 and 6 miles per hour my car says 70 but the GPS shows 64. But, not only is it different that the GPS, it is no longer accurate period. This I can't live with. You are right the unit looks good, and certainly it is better to look good than feel good. But, when it comes to my Porsche I can't live with speedometer error AND poor nav. Guess I can look cool with it installed and bring my Magellan 700 for proper speed and nav. [quote name="rychone"]I agree with MChance000. I have this installed in my Porsche 996 for the past 3 days and the route cal

Unfortunately, as I explained in my prior post it appears that all the things you mentioned don't seem to fix the problem. I have tried every permutation and there doesn't seem to be much of a difference. The installer says the road speeds only change the estimate. As I indicated, estimate skills are poor on the Z1. You can't adjust any of this on the Magellan 700 but it gives good estimates and the best route every time depending on your choice of fastest, shortest, most or least use of expressways. The Z1 doesn't seem to pay attention to any of it. In any event even if it does going to

My installer insists that isn't the case on the install. But, even so that doesn't explain the abysmal navigation. And if the problem were just "car nav" then all the companies units would be bad, but the 700 I used for comparison is cheaper and better. Car nav is something I have been using for years now. But never have I spent so much on anything that navigates so poorly...expect for perhaps one of my ex-girlfriends. But even they know 70 is faster than 35 and no stop lights is better than neighborhoods small roads.

The unit was professionally installed, by SoundAdvice (Tweeter) and the install was rechecked by the installer. I have not changed or modified anything. The CNET is a glowing regurg of the manufacturers specs, not a real test. My comments refer to real world navigation and I stand by them.

I had the Z1 installed over the Easter weekend and I plan to have it removed this week. I do not recommend this unit. In my opinion, Pioneer has spent the majority of its energy in protecting itself from liability rather than on useability and reliability. I have read that the green parking brake lead can be grounded to bypass the 'grey out' of multiple functions. The pioneer representative in the store I spoke with has bragged that they have built in speed sensors to prevent dvd and multiple nav functions use even with the ground bypassed. This appears to be true, but unfortunatly tying the Z
