Replying to: tallman1 (Feb 23, 2009 12:16 am) When the trip computer estimates the length of time for a route, it's basing it's calculations from stored data, which is on the DVD. If the DVD has errors, (and they do) that could effect the trip time the computer generates. Yep, I'm guessing here, and to me, the error would be in the DVD. The GPS may be able to accurately generate a time "as the crow flies" but when you add in roads, the GPS would need to use the DVD. I don't think there would be any adjustment that can be made to the Navi system to correct an error like this?

Replying to: mrbill1957 (Feb 23, 2009 3:05 am) Interesting. I would have guessed that the trip computer was separate from the navi since there are vehicles that have a trip computer but no navi. I've never timed it, but I thought the elapsed time was based on the engine running and that the miles were from a separate odometer on the trip computer.

Replying to: tallman1 (Feb 23, 2009 9:32 am) No Hondas have it without Navi, do they? At least, in my generation, they didn't (Gen 7, '03-07). Replies to this message: tallman1 (Feb 23, 2009 10:44 am)

Replying to: thegraduate (Feb 23, 2009 10:34 am) No, Hondas do not have a trip computer w/o navi but other cars do.

Replying to: tallman1 (Feb 23, 2009 9:32 am) I've never had a chance to play with one of the trip computers that wasn't part of a navi system. How do you enter your destination? With the Accord navi, when you enter a destination, the navi will build and display multiple routes, all with different times and miles to travel. That's alot of data crunching, so I would think it has to be getting the data from the DVD.

Replying to: mrbill1957 (Feb 23, 2009 3:08 pm) We're talking about two different things. The trip computer figures gas mileage. The display shows your instant mileage, cumulative mileage (since the last fill-up or whenever you reset it last), the range (miles you can travel with the current gas mileage you are getting), the miles you've travelled, and the time you've driven. The OP was concerned that this display did not match his/her actual mileage or time driven. The ScanGauge II is an example of an aftermarket unit you can buy for your car to provide this info. You are correct in that the DVD supplies the navi system with all the map data. Most aftermarket navi units (Garmin, etc) use computer chips to store that info and you update them by downloading data from a computer instead of using a DVD.

Replying to: tallman1 (Feb 23, 2009 4:07 pm) OK, I agree with that. A basic trip computer is different. My thoughts were with the original posts (234-236?) he was having problems with the navi mileage being off. As far as accuracy to the "trip computer" screen in the navi system on the Honda, when I refill my tank, I also reset the trip odometer. The trip computer and navi mileage on the tank agree within a 10th of a mile. Mrbill Replies to this message: tallman1 (Feb 23, 2009 5:34 pm)

Replying to: mrbill1957 (Feb 23, 2009 5:10 pm) I thought that was his/her original question too. He/she seemed to be talking about the trip computer after some clarification (post 240). The odometer on the trip computer screen and my regular odometer are always off, but not by much.... more than .1 though.

Replying to: mrbill1957 (Jan 30, 2008 10:10 am) This also happened to me a few times and I updated my disc to a 2008 version from Alpine and it still happens. The dealer wants to send the system out for repairs but will not guarantee that this will work. furthermore, my POIs are way off as well. What do you think my best option would be?

Replying to: steveyarc (Mar 20, 2009 8:48 am) Have you asked what the repair price tag is? Replacement costs are VERY high so if they think they have a cheap solution, I'd say do it but if their solution is replacement, it isn't worth it.
