#21 of 616 discrepency by montreallou Jan 26, 2004 (11:17 am)
Has anyone compared the distance traveled on the Navi system to the Trip computer to the odometer. I have heard they use different calculations. Does anyone know. I was also told it was in my manual but I have yet to find it.

Thanks for the info. Will it also slap teenagers sitting in the back to get them to shut up so you can think straight and hear the directions?

I have not yet compared the trip computer to the nav distance traveled. To be honest I have never heard this but it makes me very curious and I will check it out tomorrow if I remember.   bodble2. Unfortunitly it will not. But you will find that passengers talking during instruction is not the most frustrating. Try giving voice commands with people in the car. Never in my life have I ever thought of hitting a tree until the moment I hit that voice command button with my father or brother in the car.
#24 of 616 Anyone with info about calculation of ETA? by jime6 Feb 02, 2004 (1:58 pm)
Does anyone have a source for information on how the ETA (Estimated Time of Arrival) is calculated? I would like to know why it is so inaccurate.   I have a Garmin Streepilot III aftermarket automotive GPS that is very accurate on ETA, but my TL GPS is way off. I have even run them at the same time (talk about too many voice instructions) and find that the Garmin is usually within a minute on a 30 minute drive, and the TL is usually 5 to 9 minutes slow.   I think it is because the TL GPS starts out estimating that you will drive the speed limit on the highway and ½ the speed limit on streets (trying to calculate time at stop-lights?), but I am guessing. The Garmin keeps a “history” of the driver’s habits and I think it only considers travel time when giving estimates (not “stopped” time).   This is my only “complaint” about my Acura TL so far.   Thanks,   jime Replies to this message: midnightcowboy (Nov 04, 2004 2:21 pm)
#25 of 616 Canadian nav systems by bodble2 Feb 02, 2004 (2:24 pm)
When I had a TL demo on an overnight test drive, I played around with the nav a fair bit and generally found it user-friendly. However, I do have 2 minor complaints. One is that even in Canada the nav states everything in miles, not KM. Maybe not a huge deal but since it gives instructions such as "turn left in 1/2 mile...", or "continue on highlighted road for 2 miles...", it would be nice to be able to just take a peek at the odometer and not have to do a quich metric conversion. And second, it doesn't seem to identify bridges or tunnels. I'm thinking of situations in which the road branches in 2 different directions, and if you veer one way you go on a bridge or tunnel/underpass. It would be more helpful if the instructions were to be like "keep left to go onto bridge...".
#26 of 616 And by the way... by bodble2 Feb 02, 2004 (2:27 pm)
The owner's manual does not seem to contain instructions on operating the nav, or using voice-command. Is that on a separate manual?
#27 of 616 by aciampi Feb 02, 2004 (3:26 pm)
From what I was led to believe the way the TL computes distance ETA is by how many miles to destination and traveling at your average speed. Your Streetpiolt may be going by real time speed which is purely a guess because I know nothing about your unit. And I also don't believe the TL Nav unit knows the speed limits on perticular roads.   Bodble2. If you go into the setup screen and then select one of the menues(#1-4) I believe there is a way to change from miles to KM. Also there are about three or four manuals I think and there is one that explains a lot about how the system works and what the voice commands are.

"The owner's manual does not seem to contain instructions on operating the nav, or using voice-command. Is that on a separate manual?"   My dealer originally forgot to include it with my manuals and had to mail it to me.
#29 of 616 ETA on 2000 Odyssey by kph Feb 02, 2004 (7:12 pm)
We have done many a trip in our 2000 Odyssey Navi -- it has the same problem. It's estimate is always longer than it takes me to drive.   I had always assumed they had encoded speed limit into the database (easy enough to do) and calculated based on that. But, since the mileage remaining was accurate, I can do simple math based on my average speed and come up with a better estimate in my head.   Would be nice if it was smarter...   Now, assuming the speed limit in a TL??? Tsk tsk -- how silly of them...
#30 of 616 Canadian Nav by montreallou Feb 03, 2004 (8:07 am)
My Nav system was delivered with Km, not miles being reported. It has to be in the setup I am sure!   My complaint in Canada, is that it maintains its database with accents on the names. So Montreal for example, is not found on the search, because Montreal has an accent over the e in their DB (as it is in French). You can find it going through a list, but its very cumbersome.   Also, for some reason, when looking at POI, it can not find any Pharmacies in Montreal. It wants to send me 300k to NY.
