 So far so good, it's a good vehicle with some constraints. We are still learning by reading the manuals. Actually we are not driving this vehicle yet. We may need more time to give full review.We can't change 'navigation' unless you stop the vehicle (may be there is a way). It's relatively good vehicle, but with limited safety features. I expected to have vehicle detection system (which automatically stops if we reach too close to the vehicle), but we don't have it.We are still playing with controls.
