Our E-Golf is brand new & this is our 2nd difficulty with the camera. First it worked, then it didn't . . . eventually we were told (by salesman) that you need to make sure the hatchback is REALLY shut -- listen for two thunks close together, keep closing it until you hear the double-thunk. We did that, camera started to work, and has now been working fine for a week. Today, it suddenly stopped working & we get screen message saying "Park Pilot is not available" with only option to press OK - then message disappears. Possible causes (???): it's a rainy day, first in the life of this car; also I noticed earlier that rear wiper was automatically activated when I was in reverse AND it was raining AND front wipers were on . . . so I tried playing with reverse a bit, going into reverse when it was raining, then when it wasn't, with front wipers on, then off . . . to figure out what was cueing the rear wiper. I never did figure that out because in the midst of this the camera stopped operating. (Of course I got out and opened and closed the trunk a few times - no help from that.) Any ideas? We love the camera & want it back! BTW, we have the SE (less expensive) model, without the other fancy driving stuff, just the camera. Thanks for any help.
