Prior to this I had Einparkhilfe attempts a cheap from eBay. After a short time I pulled the fuse, the thing has sounded the alarm, and I'm not even going down. Let people just stay away from the stuff. Somewhat confused I have ordered in per parking aid. Installation is problem-free. Now after about 2 weeks I can confirm everything works great. Each obstacle is detected and signaled correctly. Even in the rain and snow is not a malfunction. Conclusion for the price a great product.
