lol. I guess at that temperature, even electrons just decide to stay someplace warm, and don't want to come out and play.
Actually, to put it in a nutshell, it has to do with the properties of semiconductor materials. They tend to not conduct, get brittle, and certain components like LCD displays can freeze and turn black.

For a time I tried using WayFinder on my phone in a large mitten but it is really hard to hear. I didn't have a bluetooth headset but I don't much like head sets when I am out traveling in the snow, sounds already being muted. Reading a couple of lines of braille at intervals when you want to be alerted to an intersection just doesn't cut it. Now that I am retired I can just choose to stay home under blizzard or cold conditions but then neither do I have need for GPS in my living room.----- Original Message ----- From: "Howard Kaufman" <wa9top@xxxxxxxxx>

I tested my old PK at minus 10 F, it worked fine. I could pull off a glove, read a line and put the bglove on. I had time for maybe two lines if I was quick. It would have been hard to have a braille only option at those temperatures, but the Braillenote and the GPS worked as well as the polar fleice arctic hood, down filled coat and mittens, snow pants, and snow boots rated to minus 50 DG F. I had long hunters underware jeans and a sweatshirt under the cold weather stuff. It all worked except I shatered a roller ball cane tip, just by hitting an ice block.So my advice, is for solid cane tips at those temperatures.To change your email settings (unsubscribe, digest only, or vacation mode):http://senderogroup.com/social_media/email.htmAdditionally, to unsubscribe send an email to gps-talkusers-request@xxxxxxxxxxxxx with "unsubscribe" in the Subject.
