I have one of those heavy duty removable tow bars fitted to my car. When I put the car in reverse, the reversing sensor system sounds off with a continous tone :ranting: because it is picking up the towbar in close poximity. Is there anyway to stop this, as I still want the reversing system to function with the towbar fitted. According to the VZ vehicle manual it says that the reversing sensor system can be adjusted by the Holden dealer to compenstate for the towbar. Has anyone had this done and what does it involved ?
