Updated to 2014.10 on Nuvi 2595, avoidances ignored

What I take away from the OP is that a map update leaves the "avoidances" intact in the unit - but ignores them after the update is completed.

I can't really immediately help because all I had in the units before the last map update were unpaved roads and I do not know a close place to simulate to see if they are being ignored.

Someone who has not yet done an update to 2014.1 could help understand if the problem exists by doing something like checking "Highways" as an avoidance just before the map update. After the update almost any "Go" would let the user check the "turns" from the top bar to see whether "highways" are being ignored and have to be reset.

The roads that I had set avoidances for were near home. When I used the "Go Home" feature, the route it programmed was not to my liking, so I blocked some of the roads to force the Garmin to route me the way I preferred to go. After updating, and using the "Go Home" function, Garmin programmed the route that I was trying to avoid. So I deleted the custom road avoidances, then programmed them back in, and the next time I used the "Go Home" setting, it took me along the preferred route.

Just in case the above makes no sense to some readers, it's because some models like the nuvi 2595, but not all nuvis, allow for Custom Avoidances where a specific road or a rectangle of area can be created as a Custom Avoidance. If your nuvi doesn't offer Custom Avoidances, then you won't need to worry about losing them upon a map update. It's left to be determined if the "standard" avoidances (like U-turns, ferries, unpaved roads, etc.) are similarly affected.

Ok, thanks to CraigW for the info on "custom road avoidances". I made the assumption - based on my 765T - that is was general avoidances the OP was talking about.

What we need now is to understand why the custom avoidances were now honored over a map install. Likely, it is because you have to use the "map" to set the custom avoidance in the first place. Would that seem right?

Now that my daughter has gotten back from vacation, I can play around with the 2595 I got her. I will be learning like a lot of others - so any tips that might need to go in the Glossary or in the Tutorials will be appreciated.

Following this thread I pull this info up on Garmin Support. See note "custom road avoidances may have to be re-set after each map update".

How do I create, edit, or delete custom avoidances on my nuvi, dezl, or zumo?

The nuvi 800, 805, 5000, 2400, 2405, 2407, 2408, 2505, 2507, 2508, 3400, 3500, 3507, and 3508 series devices, the dezl series, and the zumo 350 allow you to set up custom avoidances so that you can avoid specific areas and lengths of road.

*Note: Custom road avoidances may have to be re-set after each map update. Custom area avoidances should remain accurate and intact.

To access custom avoidances on the nuvi 800, 805, and 5000 series:

Touch Tools
Touch Settings

Touch Next
Touch a point on the map that you want to be the opposite corner of the avoid area
Touch Next
Confirm that the area you want to avoid is completely covered by the rectangular area
Touch Finish or Done

The nuvi will now avoid the area you selected.

To avoid a specific length of road:

Locate the road you would like to avoid all or part of
Touch the point on the map that will mark the beginning of the stretch of road you would like to avoid
Touch Next
Touch the point on the map that will mark the end of the stretch of road you would like to avoid
Touch Next
Confirm that the highlighted area contains the entire length of road that you would like to avoid
Touch Finish or Done

To edit or delete a custom avoidance:

Access the custom avoidance menu
Touch View Custom Avoid List (skip this step on the 2400, 2505, 3400, 3500 series, zumo 350, and dezl 760)
Touch the custom avoidance you would like to edit or delete
Touch the menu button that shows as three horizontal lines (skip this step on the 800, 805, and 5000 series)
Select the desired action
Rename will allow you to type a new name for the selected custom avoidance for easier identification
Disable/Enable will turn the selected custom avoidance off or on without permanently deleting it
Delete will permanently delete the selected avoidance

Repeat these steps as desired to edit or delete other custom avoidances.

To delete more than one custom avoidance at a time on the nuvi 2405, 2407, 2408, 2505, 2507, 2508, 3400, 3500, 3507, 3508 series devices, zumo 350, and dezl 760:

The selected custom avoidances will be deleted. Please note that after touching Delete, no confirmation message will appear. Please confirm the selections prior to touching Delete.

you beat me to it. I had that on the clipboard.

Answer is relatively new - dated 6/13/2013

And another new one that answers the OP

What are the navigational avoidances on my Garmin nuvi, LIVE, zumo, or dezl device?
Answer:
Garmin devices have an Avoidance menu where you can select various options that will adjust how your device routes you. Items with a check mark beside them will be avoided whenever possible.

*Note: Custom road avoidances may need to be re-set after each map update. Custom area avoidances should remain accurate and intact after updating maps on the device. (emphasis added)

Highways or Motorways – The Highways or Motorways avoidance will avoid highways, Interstates, freeways, motorways, and other major routes
Toll Roads or Tolls and Fees – The Toll Roads or Tolls and Fees avoidance will avoid toll roads and certain specified congestion zones

Ferries – The Ferries avoidance will avoid taking you on a route that requires a ferry crossing
Carpool Lanes or Car Share Lanes – The Carpool or Car Share Lanes avoidance will avoid routing you on lanes designated specifically for carpooling
Unpaved Roads – The Unpaved Roads avoidance will avoid taking you on unpaved roads
Custom Avoidances – Custom Avoidances is a feature available on some devices that will allow you to select specific areas or lengths of road to avoid. For a full list of devices on which this is available, and for steps on how to use it, please view the following article: https://support.garmin.com/support/searchSupport/case.faces?caseId={0f37d3e0-5440-11dd-f529-000000000000}
Please note that devices will only avoid selected items when it is possible. For example, if you have U-Turns selected as an avoidance the device may still direct you to make a U-Turn if an alternate route is not available.

1Not all of the listed avoidance options will be available on all devices. Avoidance items listed here that are not on your particular device cannot be added.

2Disabling the traffic avoidance does not disable traffic alerts from appearing on the device; however, it will not take the reported traffic incident into account when calculating routes.

Would have been nice if they would supplied answer for why it happens. Maybe update in the future will fix since they are aware of the problem.

The answer may be in

Perhaps, the area stays valid because it is based on coordinates, but the roads need to be reset because the routing engine would look at it differently in each new map.

Guessing, of course, but I linked to both of our recent posts in the Glossary.
