AMPS to 17mm Ball Joint Phone Mount Adapter

Got an AMPS-pattern mount already installed in your car but want to use a modern 17mm ball-style phone holder like iOttie or a Garmin Nuvi mount? You shouldn't have to replace the whole mounting system just to switch holders. This compact adapter bridges the gap — letting you plug a 17mm ball head directly into your existing AMPS bracket without drilling, cutting, or buying an entirely new mount.

How it works

The adapter fits the standard AMPS hole pattern (4 mm holes at 30 mm × 38 mm spacing) and provides a compatible 17 mm ball socket on the other side. Simply attach it to your existing AMPS base, snap your iOttie, Garmin Nuvi, or any other 17 mm ball-head holder on top, and you're ready to go. No tools required beyond what your existing mount already uses.

Key benefits

• Converts any AMPS-compatible mount to accept 17 mm ball-head phone and GPS holders
• Compatible with iOttie, Garmin Nuvi, and other popular 17 mm ball systems
• Saves money — no need to replace your existing AMPS dashboard or windshield base
• Solid, sturdy construction that holds its position on the road
• Compact and low-profile — won't add bulk to your setup

Where to use

• Cars with aftermarket AMPS-compatible dash mounts
• Vehicles already fitted with AMPS RAM-style bases
• Upgrading from a fixed holder to a flexible 17 mm ball system
• Anyone switching between iOttie and Garmin Nuvi-style holders
