Hi mates,
I´ve been testing to bugs.
The first one: 700i with micro USB powered .:
My 700i is firmware 15.2, since 15.X it started to swtiching off apparently randomly, but after watching it carefully I can conclude that the enviroment that cause the switch off is the following situation, while navigating a route, I decided not to take into account what the unit said , so it started to show & say (through Cardo bluetooth device) "turn back" and recalculated the route , after a number of times it switch off. If you used it as GPS it never switchs off.
The second bug:
While a route is active, if you try to create a new one, the unit freezes, no responding even the power button. The only way was taking out the battery.
This two bugs were repeated many times, every time I wanted to tigger the situation, I was successfull on it . So my conclusion was that a realtionship cause-effect was stablished.
Thank you all, if any one could say anything more I ´d be very please
