Stick the copper foil part of the antenna on the metal part of your A-pillar. Stick the remaining part of
the antenna on the windshield. Make sure to clean both spots before placing the antenna.
Attention: the copper foil must be sticked on a metal underground otherwise the signal
strength might decrease up to 30%
Wire the antenna cables by using the self-adhesive clips to secure the cables.
Afterwards put the A-pillar cover carefully back without breaking the cables.
Note: the installation may differ depending on the model of your car.
