Hi everyone ive got a problem hope someone can help. I converted a Carrera BMW M3 GT2 to Scalextric Digital using a Scalextric saloon car chip and I converted the pick up to a Scalextric quick change guide aswell. Then I tested it. I have a advanced 6 car power base and the BMW runs around the track but will not change lanes when I press the button. I get a bleep sound. What could the problem be. Thanks for reading and hope someone can help.
