APPS2Car 3" Dashboard Mounting Disks — 3-Pack Adhesive Pads for Suction-Cup Phone & GPS Mounts, 3M VHB Bond

APPS2Car 3" Dashboard Pad Mounting Disks are adhesive-backed round pads that create a smooth, flat surface for suction-cup phone and GPS mounts on car dashboards.

If your car’s dashboard is textured, curved, or otherwise unsuitable for a suction-cup holder, these 76 mm mounting disks provide a reliable place to attach suction-based phone holders and navigation mounts. Each pack contains three disks with 3M VHB GPH-160 adhesive engineered to hold in everyday driving conditions. They are designed specifically for dashboard use and are simple to install with no tools required.

How do I install the mounting disk correctly?

Installation is straightforward but important for a secure bond: choose a clean, flat, and dry spot on the dashboard, remove the backing film, press the disk in place, and allow the adhesive to set before mounting a device. Preparing the surface and giving the adhesive time to cure ensures the best hold.

• Clean area with isopropyl alcohol or mild cleaner and dry thoroughly
• Peel off protective backing and position disk on flat dashboard area
• Press firmly for about 10 seconds to seat the adhesive
• Wait 24 hours before attaching the suction-cup mount for best adhesion

Will this disk work with my suction-cup phone holder?

These disks accept suction cups up to 3 inches (76 mm) in diameter, which covers most phone holders and many small GPS mounts. They act as a smooth contact point so the suction cup can form a reliable vacuum even on dashboards that would normally prevent full suction.

• Compatible with suction cups ≤ 3" (76 mm)
• Works with common phone mounts and small GPS holders
• Not intended for windshield use or oversized suction cups

How durable is the adhesive and when should I avoid using it?

The disks use 3M VHB GPH-160 adhesive, chosen for strong, long-lasting bonding including exposure to normal vehicle temperatures. However, adhesion is optimized for smooth, flat dashboard surfaces — it will not perform well on heavily textured, oily, leather, or sharply curved areas. Each disk is single-use and should be replaced if removed.

• 3M VHB GPH-160 offers strong bonding in typical temperatures
• Not recommended for textured, leather, or uneven dashboard surfaces
• Single-use adhesive — replace disk if peeled off

Can I use these disks for multiple vehicles or as spares?

The 3-pack design makes it easy to outfit multiple cars or keep replacement disks on hand for future mounts. Because each disk is intended for a one-time installation, having extras means you can move mounts between vehicles or replace an old disk without delay.

• Three disks in one pack for multiple dashboards or backups
• Good for relocating mounts between vehicles with fresh adhesive
• Compact, low-profile and unobtrusive when installed

Who is this for: Drivers who want a dependable suction-cup mounting surface on dashboards that are otherwise unsuitable for suction mounts — especially owners of textured or curved dashboards, fleet drivers who need consistent mounting points across vehicles, and anyone who prefers a tidy, removable mounting option without permanent drilling or hardware.
