Its been getting quite cold where I live - this morning its around 20F. It might have been even colder overnight.
Do any of you take the GPS out of the car to keep it warm? Does that help extend the life of the battery?
What about summer heat?
Nope, always in the car except to update.
Went down to 16f the past weekend and high around 20f. No problem.
Gets up in the 90's sometimes in the summer. No problem, it stays in car.
Units are always in car, from the first one in 2012 until now.
All Garmin auto GPSs operate mainly on 12 volts from the cigar lighter outlet in the car. If 12 volts is on, the GPS will navigate and charge the battery at the same time. This is assuming the car is used regularly even in winter.
If the car is little used, the battery may slowly discharge. It would be better to charge it with a wall charger and shut down the GPS, not just sleep.
In the summer, do not leave it in the sun on the dashboard, since high heat can damage the battery long-term.
I usually keep mine in the car unless I'm updating as well, but for the past two days, I noticed that the GPS boots up (the progress bar) when I start my car. This probably meant that overnight, the battery got so weak it couldn't stay in sleep.
Then I read that charging a lithium ion below freezing isn't a great idea for its longevity. Heat can also shorten battery life too.
Just curious if there is any real-life evidence about shortened battery longevity just by using the car charger when the GPS battery is below freezing.
I haven't heard that.
For heat I have window rain guards and when parked my windows are cracked open except for snow forecasts. At home only I cover the GPS with a white wash cloth. It isn't practical to do the same for the dash camera.
For cold I do nothing. I live in a temperate climate and near home I don't think of it. When I used to ski extended periods of as low as -10°F weren't a problem. If I moved to somewhere where the temperature got to -40° then I'd have to do a lot of learning.
When I get home I unfailingly bring my GPS unit into the house just to avoid potential temperature extremes. I live in northeast Ohio where winter temps can go down to 0 degrees and summer temps go up to the high 90's so I just bring it inside.
I bring min in daily, independent of the temperature. Keeps the car from getting broken into. Good neighborhood (sarcasm). Have a few dents and scratches on the door and window from previous attempts. If I'm not going to use my 3597 for a few days, I perform a hard shutdown to preserve the battery.

I do the same. Except that for retired me, I never know when I'll next use the car and GPS so I do a shutdown all the time. I also always power up the GPS on any drive even when I know the route and don't expect to be delayed by traffic where the smartphone app send traffic info to the GPS so that the battery gets a bit of a charge. I don't know why, but my 3597 (and DriveLuxe 51) seems to lose charge over time even when fully powered down.
