Hi, all... I am really enjoying traveling around on my Roadsmith trike. However, now that the weather is heating up, my phone is overheating when I have it connected as a GPS. I have a mount on my handlebar. Yesterday, it hit 100 degrees and my phone stopped working until I could cool it down. Obviously, this isn't going to be a reliable solution for me going forward (I ride in Arizona and Nevada). Can anyone make a good recommendation on a GPS unit that will work well in extreme heat and perhaps rain? I'd like a good reliable solution as we travel on the bike quite a bit. Thanks!
