Firstly I want to thank the CD team for allowing me to be the first beta tester for the newly released and shiny CarDongle v1.5! I haven't tested much so far, but I can confirm the GPS does work, and Google Maps was able to route me around on a quick 10min drive in my neighborhood. Complete with rerouting when I purposely took the wrong turn. Things were a little slow to load, but that could be due to my Cell Phone provider and not the device itself.
It saw 22 satellites and connected to 11 of them:
It did get quite hot though, but didn't shut down. I of course didn't try any Netflix, YouTube, or other streaming services as those aren't the reason I bought the device, but if you would like to me to test something, call it out and I'll do my best to at least attempt it.
