The parking sensors on the front/rear bars not show on the device (on the new device it shows only the " ! " sign and nothing else). Which makes me uncomfortable parking in small spaces. It is very important to be able to benefit from the parking aid given by the parking sensors. I reported it to the seller.But nothing! Periodically, XTRONS product shuts down without any control over it until its power supply is stopped. While listening to the radio, the device turned off. I found, after restart, that the sound can only be heard in the speakers in front without being able to adjust. The seller said "Don't worried, we will help you solve it. Stay calm we solve", 10 days passed and I did not receive the solution although I kept coming back with the request to be able to use the product. I do not expect support from the seller. It seems that I was tricked, that I lost money on a product that I can't use.
Very easy to setup. Installed on a Golf V.
