1. When external power is connected the unit starts up. When external power is removed the unit starts up. So when I charge it in my car and the external power is switched on and off, the unit ends up turned on and when I go to use it the battery is dead.
2. When riding a familiar road, the upcoming elevation profile is not shown (some undetermined profile is shown). It will show the profile IF a route had been loaded and is being followed but otherwise without the route loaded the elevation profile shown is nonsense. Why doesn't the unit show the proper profile while riding? The unit obviously know where you are and where you are heading. Jeez....
