Hey Waterhond
You take the N1(NE) from Jo-burg to centurion, From the N1 you take the off ramp that says M19(NW)(John Voster), at the robot above the off ramp you take a right to cross over the N1. After crossing the N1 you get another robot (West Avenue) turn left there and take the next street to the right(Bellingham Street). Take this street all the way to the boom gate, enter through the boom gate and go straight. Bass World will be in front of you.
Hope this helps and hope it is correct.
Happy Shopping
