I was really excited to travel to Seattle and Vancouver with my new Nuvi 760 this past week. I loaded a speed trap and red light camera file, a Starbuck POI and installed all of the upgrades. I was expecting this thing to tell me exactly where to go. I soon found out that it would not be so straight forward. Every once in a while I would look at the next instructions and it would say turn left in 750 meters or whatever number it said. Then out of the blue it would say recalculating. Some time it would tell me to keep going for the remainder of the distance as it realized that I was on the right road and other time it would tell me to turn a certain way to get back on route. I would ignore it and it would eventually realize that I was still on the right route but it would confuse me. I loaded my speed trap manually with +5 km/h so it would only warn me if I was going 5 km/h over the speed limit but the poi file I used did not have speed limits for Vancouver. So every time I was driving more then 5 km/h close to a speed trap and God knows they are everywhere in Vancouver it would warn me over and over again. Same goes for Starbucks in Vancouver and Seattle. They are everywhere!!!
I can fix my POI but I am not sure about the recalculating issue. Is it common on all models or is the 760 more susceptible to it?
I did experience some firmware problems that caused it to hang and I would have to turn it off and then on again. but not the recalculating problem. I bricked it trying to go back to a previous vers of software and now have a 770 without problems... well it stutters on occasion..
Edit: Does the problem persist? Or was it just on the one excursion?
...Every once in a while I would look at the next instructions and it would say turn left in 750 meters or whatever number it said. Then out of the blue it would say recalculating.
Could be the traffic avoidance kicking in and out on a long route or the result of misinterpreting your actual location (see next item)

How far did the GPS thought you were from your actual location? I've seen something similar a few times: When two roads are close to each other (like the access road and the freeway) my GPS (770) is sometimes confused whether I'm on the freeway or the parallel access road. I suppose this is a map error but I'm not sure. I'm talking about 100-200 feet here (30-60m), not much more. If your unit believe you're way off from your current location, it might be defective.

How do you do that? I don't know how to tell the POI loader to "add" 5 to the data in the POI file.
I am not sure, but are you running 2009 maps? I had that problem with my c330 with 2007 maps - and they were not always the best. The highway would jog - and the gps didn't show a jog - Then it would try and get me back on route. The other problem is when the gps thinks there is a jog, or the highway turns and it doesn't - will do the same thing.
A trick is that you can tap the green bar at the top and it will show you a list of directions, at the bottom is SHOW MAP. I "almost" always check this before I start a route, and make sure it looks ok. The other trick is tapping the lower right hand tab and it will show you your next turns.
I am not quite sure that this is your problem, but let me know. Your gps is a guide, and probably 85% accurate on streets and such. I have increased my faith in its accuracy overtime. You just have to get used to it.

Losing track of where you are is an issue of accuracy -- either reception or faulty gps. Do you have the unit positioned where it has a clear view of the sky (not down on the console, high on the windshield, or in passenger's lap)? Some vehicles are known to have windshields that block the signal and that can necessitate an external antenna. Check the reported accuracy (reported in feet) both inside the vehicle and outside -- that will tell you how much is being blocked.
I predict you will soon eliminate alerts on anything other than perhaps cameras and rest areas -- they will drive you crazy.
ive had that a few times on my 760 it always cleared up very fast
I've had my 750 tell me correctly to get off the local xway onto a parallel access road, then incorrectly tell me to get back on the xway, then immediately back off again!! - all within 100 yds. This was in front of work so I believe that my psychic energy was influencing my Garmin to lead me AWAY from work because I really didn't want to be there anyway??
Follow Felix's and a_user's advice located here:

If you're talking about Vancouver BC, rather than Vancouver, WA, then the reason there are no speed limits in the file is probably because there are no fixed speed cams in Vancouver. There are red light cameras and mobile cops trying to make their quota towards the end of the month - but no fixed speed cams. If you put a speed alert in the files it was probably going off for red light cams (or Starbucks! ).
I bought one of these at Costco last year and was immediately dissatisfied. I have always had Garmin brand Gps's and expected better. The Nuvi would send me down a side street and then bring me back to the same road I was on. It would send me through the middle of town instead of using the freeway. I did a comparison of the routing of the Nuvi and my GPSMAP 76Csx and the GPSMAP was superior. After this test, I returned it to Costco. I ended up buying a Magellan 4050 with trip kit and I have been happy with it.
my 2 cents
geez. how much better would a 765T be?
and what does that T mean??
I have to wonder how your avoidance's were set.. I have never had those problems with my 760... But isn't Costco great about making returns?
All I can see in that thread is how to modify the POI file itself, either with Excel or the now-retired POI II Verifier. The OP wrote "I loaded ... manually with +5..." which I interpreted as using the POI Loader. That what I was trying to find out about.
