I've had the 522GW for a few weeks, and overall it's not bad, but parking mode is utterly terrible, as it causes the dash cam to crash, freeze, and out right refuses to record, it looks like it needs an update to stabilize the software a bit, as with parking mode turned on the camera is unusable, and i only found this out after driving 200-300 miles and needed to press the protect button for it to nothing.
