GV300 is a nice piece of hardware, there are a lot of firmware versions out there, that's is the first point, try to get most updated fw in your units, about the reboots, there is a specific tab in the configuration software that allows choosing differents behaviours , example, reset by each N time of Day or reset each ignition detection and so on.
i always I did choose periodic reboots, regarding to server configuration it is very dependent of the carrier's network, but as hard they can be use forced mode, if the carrier is a piece of cake then use TCP Long, in order to keep connection as longer as you can
in Wialon, i've gv300 units are in TCP Short forced mode, it works just for me, but in tehory any mode will be supported including UDP/IP
the hardware suppot a lot of aditionals add .ons, cameras temp sensors and also CAN Data шина as Omnicomm Fuel Sensor protocol are integrated at firmware level.
the only think don't like is poor RSSI reception , it sick me !, lower rssi i ever seen in other equipment, if you can live with it, may be you'll happy !
