Slow tracking after Nov map update

i think i can see same thing (when using 3D mode) after most recent (and my first) map update for US. anybody else seeing this ? any patches for this ?

i'm using garmin 275 (US+EU maps).

I AM NOT HAVING ANY TRUBLE AFTER UPDATING. I have only notice that there is 3mph difference between you car speed and the speed GPS shows for that perticular moment. Not when you go on same speed for a long time. i think thats normal.satellite takes that much time to track you.

I ahve a 660 and have had no problems witht he new maps. I travel the USA and have used it in many areas with no problems. In fact lock on seems quicker.

No problem with the update on the 265wt.

One user found that by turning the 3-D map off, the response improved to where there was no discernible lag. Not having one of those units, I am not that familiar with the installed maps, but it is the MAP and not the display.

exactly, it work much faster after 3D mode off, however I prefer using the 3D though ...
I have this unit since a short time, but read also about some other users having trouble with 3D mode and new map update for US.

Try a hard reset after every map update and firmware update...

That being said, the map updates always includes a forced firmware update on your unit if it does not contain the latest version. And firmware updates have been know to cause new problems along with fixing old problems.

As I mentioned, it's always a good idea to do a hard reset on the unit to clear out any funkiness in the unit.

thanks, will give it a shot!

I have to agree 100%

After my 1st couple of updates, I experienced some quirky behavior and then saw a post here suggesting a hard reset. That cured the odd behavior and I've made it a practice ever since of performing a hard reset after any updates and have not experienced any issues since.

I really think Garmin should suggest a hard reset after any update and also include the steps to backup and restore the Favorites as they often are flushed during the reset.

Be sure to see the link DorkusNimrod included in his post. He did an excellent job of outlining the steps.

How do you do a hard reset? I have a 755t that doesn't have a removeable battery.

This is it:

I'll give this a try and see how it works out. I really prefer 3D view and would rather not give it up.

Following my first map update (and OS update 2.3 -> 3.0) my new Nuvi 1690 displays a similar problem: "no map data" message when selecting a destination and slow tracking of basic map (no map detail"

I tried the above hard reset without improvement. Any ideas?
