Cold = Slow (Very Slow) Calculation

Over the holidays I went to Niagara Falls. I had preprogrammed my route into my GPSr. I usually leave the unit in the glove box and only take it out when I need it. Well on this day when I selected my route on the GPS it stayed in calculating mode for over 40 minutes. I then selected a route that I have gone to in the past and that worked fine. After many reboots and verbal persuasion if finally calculated the route when I got within 30 min of my destination. I now bring the GPS inside with me. Seems the GPS doesn't like the cold. LOL
Electricity
So, electricity doesn't flow at Canadian temperatures, eh!
I just couldn't resist.

It is true
I have seen other posts about this on this site in the past. Always best to not leave in the car (for theft reasons too), although not always easy to remember.
cold never helps batteries.
cold never helps batteries. But i have had this issue before when I was in California on a trip. Took about 20 minutes for it to finish from 99% calculating....
I haven't seen it to those
I haven't seen it to those extremes, but it does seem like the thought process slows down in colder weather.

Maybe he was in Niagara Falls, New York
Couldn't resist either.

Canadian Weather
I am one of those people that leaves my GPS in my car almost all the time - summer and winter. I don't usually rely on the battery and plug it in when in use.
I admit it can get cold out here on the Canadian Prairie (listen to Randy Bachman and Neil Young sing about Portage and Main 50 below in Prairie Town
). The GPS is slow to start up but I have not had much trouble with calculating a route.
And by the way, it will be +16 Celsius tomorrow in las Vegas, and +13 Celsius up here... just like summer
Used the DC adapter
The irritating part about this is that I wasn't using the battery function (I had plugged the unit into the cigarette power adapter). It was just slow to calculate the route (new route first time). As I stated previously an often used route worked fine.

Route or current location
Was it slow in calculating the route, or did it just take a long time to determine current position?
If you shut it off in Virginia, and turn it back on in Detroit, a GPSr takes much longer to determine/confirm current location that if you turn it on at the same location you last turned it off.
It can't calculate a route until it knows its current location.

Just not calculating

Just slow to calculate the route. It was showing my current driving position and anouncing various alerts as normal. Just not defining the newly set destination route.

If I am understanding your statement correctly, this was a newly created route. Maybe there was a problem with this route since a route you went to in the past worked fine.

another option
I'm not sure where you are coming from or going, but if you were in Canada and heading to the US and have it set to avoid tolls, it could take a long time to calculate as it could navigate you a long way around the lake. I've noticed some very long calculation times due to the avoidence turned on with a limited set of alternatives.

Interesting. Never thought
Interesting. Never thought of this before. Helps explain few concerns I had.
Probably a bad connection...
Probably a bad connection... Cold solder joint or some contact issue. It needs to heat up and expand to close that small gap. Had that problem once with a Tomtom w/SD card and maps. It would'nt read the maps right away off the SD card when it was cold outside during winter. But no problem during the summer.
operating temperature specification
Garmin does specify the operating temperature of 32°F to 140°F (0°C to 60°C). Don't expect the unit will operate well when temperature is getting close or even outside this range. The casualty of the price war that almost no one cares until you are lost and freezing in the snow where you need the GPS the most.
In the old days, many Garmin GPS units did meet certain Military Specifications so they had a much better temperature operating range from 5°F to 158°F (-15°C to 70°C).
