The arrival time on ANY GPS is calculated on the speed limits of the roads on your route. Then as you drive it updates based on your average speed. This means your arrival time is simply an estimate, but one that changes constantly due to real world realities. It starts to get close only as you near your destination.

I'm not sure why you would expect anything else from a GPS device??? How do you think it should work?

Yesterday ours was WAY off - a 90 minute route showing as something like 250 minutes. Turned out we had 1-2 other destinations previously loaded that when we entered our destination it just tacked them on. In my normal vehicle GPS it asks if you want to add or replace. This one has no such request that I ever saw.

I use my garmin in motorhome also. It gives a much better estimated arrival time.

My Garmin is just about spot on when it comes to arrival time. I do notice that the speed limit announcements are not correct. Always thought this may have something to do with it. To be two hours or more off on a three hour trip is not acceptable. I have had several GPS and they were never this far off. I would expect much better than what I have gotten from a cheaper GPS.

On the Jensen, if you don't trust the arrival time, you can touch it and switch to remaining distance. You can then do your own math. Other than city traffic situations, I usually just divide by 50 for a good estimate almost no matter what. Even if the speed limit is 65 the math usually doesn't work out that way due to starts, stops, meals and bathroom breaks, toll booths, relatives or work issues calling right when you need to get back on the road, whatever...

Ours has never been that far off at the start of a trip. Sure it's off but something is not right if it's 2-hours off for a 3-hour trip. Sounds like a routing error of some kind.

Went on a 3 hour trip this weekend and the GPS was over 1 hour off. No stops, going 65 miles an hour. I realize that it is an estimate, but my Garmin on the same trip (used side by side) was just over 5 minutes off. What I have noticed is that the speed limit notification is off considerably. The speed limit on I 10 is 70 mph, the speed limit on the GPS said it was 50 mph. Can this be adjusted or corrected. Would love to hear from Jenson, but get no response from them. This problem has been from day one.

The posted speed limit info displayed is in the GPS database so it will take a software update to correct it.

I have the current updates and the freeway speed limits are still way off - 55mph on hwy 5 where it's actually 70mph.
