I have just finished a 6000 mile trip from Vancouver Island to Niagara Falls and back. Towed my 2006 Mazda MX 5 convertible with a 6 speed standard transmission with no problems. To disconnect the steering wheel lock, put key on the ignition, turn to on, steering wheel will unlock, turn key to off. Do not take key out of ignition and the steering wheel will turn freely, also the mileage towed will not register. PS I tow it behind my 33 foot A class motorhome with no problems. Barry G
