Good and not so Good on trip

Thanks for the info.

Nice report and very much in line with what I would have expected.

And you drove 2200 miles with only 5 hours of music?

The issue of the Nuvi telling you to take the turnouts sounds like you may have had your navigation preference set to 'Shortest'.

We too just finished a trip across Canada with or nuvi 255w and had exactly the same experiences. Those strange turnouts happen all along Highway 1 and other places and our nuvi is set to Fastest.

On the gps not staying stuck, the simple solution for me was to spray a tiny bit of PAM on the rubber mount. It does leave a tiny ring that's easily wiped off when removing the GPS but well worth not having to hop around in our motorhome chasing a bouncing nuvi.

"And you drove 2200 miles with only 5 hours of music?"

Well I had it set on random play and I didn't tire of it until on the way home. I had made 4 CDs with mp3 music (about 3-4hours each) and played those on the way home. Of course to play the cd's I had to unplug the Aux from the radio and play the sound from the nuvi through its own speaker. That worked so well I'm not sure I will use the Aux setup and the micro card for music in the future.

I did have a problem with sound at times but I was the cause. Everytime I needed to program the next leg into the nuvi I would turn the sound off while
doing the setup. My dog goes crazy with the insipid beeping of the unit everytime you poke it. We blew through two intersection because I forgot to turn the sound back on when I hooked it back up in the truck.

I don't know off hand what routing feature I had on but I do know she did not route me through turn outs in the US. She only did it in Canada.

BTW that brings up another minor problem I have. Her decisions of what are and are not turns is not consistent. I noticed it the first time in San Diego on I-5. She would many times show a turn ahead when in fact it was off ramps going off to the right. The same thing happened on this trip. She would indicate turn aheads when it was at T intersection and you just needed to keep straight to stay on route. My built in GPS in my toyota suffers from the same problem at times. I am now use to it and it is a minor problem. But it was a little unnerving at first when you know you stay on route for say 80 miles and shes showing a turn 20 miles ahead. Is she taking you some place else or is it not really a turn?

Your adventure is similar with mine. My trip was from southern Ontario to Clearwater along I75. My garmin 670 did well going south I did not have problems, but going north I found out that you have to be careful.
Garmin 670 does not have route capability I have to program each point individually.
I divided the journey north into 3 stages...bad idea. The first leg was not bad. I plan to stop at a rest area north of Atlanta and that was ok. The second leg I plan for Windsor, Ontario, but in the middle of the leg I stopped and my gps turned off. I restarted and changed the point to the Cincinnati...bad idea.
Imagine driving at night and raining like crazy. The gps directed me to exit from the I75 to a side road going along country roads. I exited and realized I was on a wrong pad. I turned around and enter I75 again, and again directed me to the next exit. I realized that something was not right. I changed the point to Windsor and with that I did not have any more wrong turns.
That is a bit of inconvenience, but I learned that it is wise to familiarize yourself with the route you take.

its a mixed bag. ive seen new canadian bridges / highways not make it on garmin. ive seen old routes still show up. the US is updated way more frequently than canada.

I think the level of detail depnds on the the data source (municipalities) rather than the GPS manufacturer (in this case Garmin). I have noticed that some urban areas (Calgary) are much better mapped out than other places (Edmonton, Red Deer). And in rural areas, service roads to oil/gas well sites are better mapped than many municipal roads. My suscpicion is that the level of detail depends on how advanced the local government is in the use of GIS systems and satellite technology.

Nice report, thanks.

When you say you changed your route to Cincinnati did you input an exact address or POI in that City? Simply entering the city will default to the center of town. That being the case this may have been why the Nuvi continued to ask you to exit I-75.

Just moved to Calgary and my Nuvi 350 in holding up okay. There are some roads in newer development not on the map, but very satisfied with it so far. We traveled around 9500 km last year from Winnipeg to PEI and back and GPS saved us many times and brought down our stress level to minimal. Best $200 I have ever spent on car stuff.

I did the point for the border of Ohio and Kentucky on I75.
