Q1: The suction cup mount can't attach to my dash.
A: 1. The suction cup mount is great for flat surface, not for curved, soft, plush fabrics, or bumpy surface.
2. Make sure the dash surface is clean. If the suction mount get dirty, you can wash it and let it dry, then you can use it again.
3. The fixed disc needs to be pressed for 1 minute and then left to stand for 1 hour for better adhension.
4. If you got a heavy phone, you can let the long arm lean against the edge of dashboard to support your phone.
