Oldgeezer on freel2 has road hawk and has done a thread to compare to MI-Witness

Had mine for three months now (RoadHawk HD)
Very pleased with it, in 1080 the definition is very good,have it on continuous with 32gb card
but have the events turned of as the roads around here kept triggering it.
GPS does take a while to connect,but once found quickly reconnects after
Didn't want the hassle of hard wiring,which you can by buying the kit.
Had enough cable to run around the top of the screen and the trim by the headlining to the rear aux plug
which is ignition on
