I purchased hum a while ago and got rid of it. Although it did connect my car to my phone it didnt do a few things I wanted it to do. First of all the unit is not its own phone. It has the capabilities to call 911 and contact support, but I want to use that over using my own phone during a drive and if I forget my phone for some reason I can still call someone. Second, it does not have live data capabilities. That is the first thing I wanted it for! I am a do it yourself kind of person and it did not give me live data about my car. I feel like it should be able to do all OBD capabilities. Speed, Voltage, Fuel Economy, RPMs, etc. Other than that it is a good system. But not worth me paying $50 and $10 a month when I can pay $99 once for all but calling 911 and support, and all the features I mentioned above.
