Nuvi anomaly(ies)

 

Had an interesting weekend with my 2597. Planned a last minute road trip to Boston from Ottawa, ON, so went about setting up a route on the device, however, could not choose anything in Boston (or Mass). Found what I wanted under cities, selected GO, but it took a long time to calculate the route; ended up being an additional 2000km, taking me to northern Quebec, Maine and New Hanpshire.

Then set up a route using MapSource which looked okay, however, when downloaded to the 2597, ended up being approx 2000km, following the same route above.

When we got to Vermont, tried setting a route to Boston again, but again routed me through Quebec, Maine and New Hampshire.

When in Boston, tried to set a route to Home, but it routed me through New Hampshire, Main, New Brunswick, Quebec, again about 2000km extra.

Tried again after re-entering Canada, but still wanted to route me through the previously mentioned route.

Fortunately my sister-in-law had a Magellan which filled the bill.

Thinking a hard reset might be in order.

Sounds like "Avoid Tolls" is checked in Preferences.

Nope, checked that...

Nope, checked that; I've gone through lots of toll booths before with no issues.

OK, the #1 cause is ruled out and we assume you have no other odd avoidances and especially have no custom avoidance that could come into play. How about the map? Is your device's current map all of North America? If not, what subset of North America do you have installed? It seems doubtful that your nuvi doesn't have the full map but it's worth asking for completeness. Can we also assume your nuvi when powered up has a good satellite lock and your nuvi's current location is actually where you are? Does the problem occur only when transferring a route from a computer to the device or does the problem remain if you try a simply device-made WhereTo destination?

I'm still wondering about #1. If the Tolls avoidance is set, you still could have a route that includes a toll if it is the only way to reach the destination and that could explain the tolls you've seen with the device in the past. But with tolls set and a way (even one adding 2000km) can be created, that'll be the route chosen because the nuvi wants to honor your request. Can you check your avoidances and tell us which avoidances are checked in your device?

Then again, there's no harm in trying the hard reset.

Try the following settings for Navigation Avoidance make sure no check mark in Tools and Fees and Highways ,other settings your preference. For Calculation Mode select Faster Time.Under Traffic select Optimize Route On Request. For Traffic Trends members have reported better results with the check mark removed

Strange

I have a 2797, essentially the same unit except for the 7" screen.

I just did a route from Ottawa to Boston and it simply had me go via Montreal and then south to Boston via I-89 for a total distance of 690km and travel time of 6 hrs 50 min.

I do have the 2017.2 mapset.

failed map installation

Could be the map installation did not complete properly. Remember in another thread you had a problem with a bad USB connection related to Windows 10? That could have created an intermittent USB connection last time the map was updated.

I typically have my 2597 connected all the time. I've noticed lately that when I turn my car off for even a few minutes, the unit goes through a full start-up, i.e. reloads maps etc.

This is not proper behavior for a nuvi. It should sleep and not fully reboot when the 12 volt power goes off and back on. It could be that the nuvi battery is mostly discharged if the cigar lighter connection is intermittent.

If the map update process was started with the battery in a discharged state, the map update could have failed because of a lack of power. A computer USB port does not supply enough current to both run the update and charge the battery at the same time.

Obtain a Garmin wall charger and charge the nuvi for five hours. No matter what remedy anyone recommends, the battery must be charged for it to be successful.

If there is a copy of the map on the PC, delete it because it could be corrupt. Use the original Garmin USB cable and run Garmin Express to reinstall the map update.

Make sure the PC doesn't go to sleep - change the power management settings to "constant on." Make sure there is a constant internet connection. If the PC is a laptop make sure its battery is fully charged. Watch the entire map update process to make sure it goes properly and completes.
