sports shooter Posted December 6, 2006 Report Share Posted December 6, 2006 Is there any way to calibrate the distination time of arrivial/time of trip in the Z1? My new unit is off by 50% at least. I can figure about half of the time it shows. My Garmin was right on the money, I was amazed by its accuracy. Quote Link to post Share on other sites
tillithz Posted December 6, 2006 Report Share Posted December 6, 2006 no. there is no calibration, the z1 takes in account a rating for which the roads you travel. For example, a 4 lane street would typically yield a faster rating if you will, while a residential street would have a slower rating. the avic's do not take in consideration the local traffic flow, construction, or detours, its merely a rating system.

Agro Posted December 6, 2006 Report Share Posted December 6, 2006 Under regional settings there is your average speed for highway, street, etc. in there. that may be how it calculates the different road types with time. I set my freeway to 85 Quote Link to post Share on other sites
tillithz Posted December 6, 2006 Report Share Posted December 6, 2006 I called pioneer a month or so ago about this and was given the "road ratings" explanation. Quote Link to post Share on other sites
sports shooter Posted December 8, 2006 Author Report Share Posted December 8, 2006 Thanks for the replys. I must admit that I'm getting very dissapointed in this unit. The times are off as I just mentioned and it hasn't given me good route so far. My Garmin was right on the money in these features. I though I would be stepping up by getting the Z1, but in stead it appears as thought I've spent a lot of money to step backwards. Quote Link to post Share on other sites
bdmpastx Posted December 8, 2006 Report Share Posted December 8, 2006 Most people with Garmins feel the same way. You are not alone. Garmin makes a real GPS. Quote Link to post Share on other sites
sports shooter Posted December 9, 2006 Author Report Share Posted December 9, 2006 I understand how it is calculated. I could take a 8-12 hour trips with my Garmin and it would tell me exacly what time I would arrive. ya, it would adjust the time when you stopped for gas or rest areas etc, but I would arrive exactly as it had forcasted. With the Z1 I arrive and it is telling me I will get there in 10 more minutes! It doesn't even come close. When I was on a short trip 1-2 hours, I could call ahead tell them when I would arrive and/or know if I was going to be a couple of minutes late for a meeting or whatever, but not now.

mrbrent Posted December 14, 2006 Report Share Posted December 14, 2006 Destination time SUCKS. Quote Link to post Share on other sites
tillithz Posted December 14, 2006 Report Share Posted December 14, 2006 I see that the unit is off by about 25%-33% but a mental note since I drive faster then posted limits usually fixes that. Quote Link to post Share on other sites
cntrylvr79 Posted December 15, 2006 Report Share Posted December 15, 2006 Mine's normally dead on balls accurate. Then again I rarely speed. It's setup 30,40,60. Quote Link to post Share on other sites
sports shooter Posted December 15, 2006 Author Report Share Posted December 15, 2006 You state that yours is set at 30,40,60 - is that impling that there is a place/way to set the normal driving speeds for your area, within the unit? If that's the case, maybe I need to check into that and how to set it up properly. Quote Link to post Share on other sites
sports shooter Posted December 15, 2006 Author Report Share Posted December 15, 2006 I did some quick checking and found where to reset the speeds. I believe this will make big differerance in arrival times. I know how long it takes to get to most of my destinations in reality, so I can see what it tells me and then make adjustments on the settings to fine tune what comes out correct. I'm not a big speeder, but I usually will set the cruise control for 5mph over the speed limit, so for now, I set mine at 50, 60, 75 and see how close that comes. Thanks for getting me on track, you all are super and willing to help, I appreciate that! Quote Link to post Share on other sites
whtcrxghst Posted December 15, 2006 Report Share Posted December 15, 2006 I thought this thread was a bit strange. Don't use the nav on my Z1 in my personal car all that much, but I use the D1 in my work truck constantly and the ETA is almost always very accurate. Don't really see why the Z1 is off 33% as mentioned before and mine is maybe 5%. Weird Quote Link to post Share on other sites
