New to this, so here goes. Just purchased a thinkware f750 2 channel system, at first was very happy until I noticed that when I start the system up it goes into parking mode, even when car is moving? It will stay on until it switches off when car battery drops to 12.3 v. To start the system up , it has to be manuallyvturned on, goes through its usual start up rituals, says continuous recording is starting, then a few seconds goes into parking mode?? Any ideas would be appreciated, thanks in advance.
