Garmin RV 760LMT arrival time to destination way off

My Garmin is pretty accurate and recalculates the arrival time throughout the trip. It's usually withing a few minutes. Stop for a half hour and it adds it on to the time. I don't use the RV model, just a 1450, but with low clearances added it does everything I need it to do.

The arrival time is calculated on the type of road and the speed limits set for those roads in the map software. What it does not know about and does not take into account are how many traffic lights there are, how long you will be stopped at lights, how much under or over the speed limit you will travel. It does make adjustments as you travel and but really just takes that time you are at a certain point into account and then puts in what I stated above for the rest of the trip. Sometimes it averages out close to the actual arrival time and sometimes it is off. It is just an estimate and nothing to take very seriously.

As with so many of our electronic toys,when all else fails...Reboot!
Glad you got it working properly.

Does that mean that the arrival time it gave you as you started was off by 30 minutes compared to actual arrival time? Or was the actual arrival time off by 30 minutes compared to the arrival time that was showing on the GPS when you arrived? There may be some confusion as to the actual numbers.

I simply can't imagine how it can be that far off. The three Nuvi's I've used are always within a couple of minutes.

Well my 760 and multiple other users don't see what you are claiming so something is astray and I sort of doubt it's the GPS since just to have that function off doesn't make sense to me.

My RV760 is pretty close on arrival time.It it were off,I probably would not notice anyway.
If it were off 30 minutes in 102 miles,(and I noticed)I would give Garmin a call.

I've never entered any driving speeds anywhere and our Nuvi 465T is usually within a minute or two of correct arrival time. But that arrival time is taken just before we get to our destination. The time constantly changes as travel speeds and times change.

I just ordered the garmin 2597,,,,,have to see if I can learn it too, never had one
