Okay, I'm home.
And no, I didn't get all the pictures I wanted.
I drove to the CAN-AM dealer where I bought my Spyder.
It's about 70 miles, and 1 hour and 2 minutes from where I live.
1. I disconnected the GPS from the power cable I had connected to the USB connection in the glove box.
2. I drove the 70 miles to the dealer.
The GPS powered itself off a couple of miles before I got to the dealer, well short of the time I expected it to operate on battery power.
I suspect that connecting both my phone and helmet headset via bluetooth to the GPS unit caused a bigger power draw than just using it to display navigation information.
I spent about an hour at the dealer, first waiting for the salesman since he was with a customer when I got there, and then waiting while he was in his managers office talking about the offer letter.
I think I was the last customer to leave the building, as they officially closed while I was there. When the salesman walked me out to my Spyder he held the door open for several of his co-workers who were leaving.
He then walked around my Spyder and asked me questions about what I liked and didn't like, and asked if I'd turn it on for him.
He was really impressed by the large dash display, and told me that while he'd read all the sales information, he'd never actually seen the Spyder's larger display when it was turned on.
I reconnected the GPS to the cable in the glove box while the salesman was looking at my Spyder and asking questions, and when I turned on the Spyder's Key, the display lit up, but it did not turn on.
The displayed xhowed the word "Garmin" and directly below it was a red battery icon. This was not the battery icon that normally displays in the upper right, it was in the center of the screen.
About 1/2 way home there was some crackling in the earphones of helmet's headset, and when I looked down I saw the typical Garmin display when you power it on while it has a USB connected to it. The question it asks is whether you want to enter file transfer mode (to transfer updates from your computer), and displays a Cancel and a Continue button. I fat fingered it while trying to drive, and hit the wrong button. So I had to find some place to pull over so I could turn the GPS off and back on, and correctly answer the question and allow it to function as a GPS.
I had found a very wide shoulder on an off ramp, and had pulled over and turned on the hazard flashers.
And then I got the first surprise of the day.
A guy pulled up in a car next to me, rolled down his passenger window, and asked me if I was okay and if I needed help.
I thanked him, and told him no, that I was fine.
He said "I'm glad to hear that." and drove off.
The GPS was working fine from that point on, although it didn't automatically pair with my headset when it restarted, so I wasn't able to hear the directions, although I could see the route on the display.
And then the Low Fuel light came on on the dash.
The next exit was one of the places I can get off to get home, although it's not the one I normally use.
I know there are a couple of gas stations there, so I got off, and pulled into station and started filling up.
And then I got my second surprise of the day.
There was a guy filling up his truck at the next pump over, and he saw me and asked "Is that a can-am?"
When I said yes, he got a big smile on his face and walked over to check it out.
And then he told me that he used to have one, but he sold it "more than 10 years ago."
He then smiled at me, looked at my Spyder again, and as he walked back to his truck mumbled something about needing another one.
When I pulled into the garage and shut down the Spyder, the GPS also turned off. So I unplugged the power cable from the back of the GPS, pressed the power button to turn it back on, and took this picture:
So that's how much charge it received from the USB cable in the glove box on the ride home.
