Arkon’s XLRMAMPSMET premium 4-Hole AMPS drill base mount features Arkon’s RoadVise XL large phone and midsize tablet holder, which holds devices (even those with skins and ruggedized cases) up to 5” wide. The mount is compatible with Apple iPhone 11 Pro Max, iPhone 11 Pro, iPhone 11, iPhone XS Max, iPhone XS, and iPhone XR, iPhone X, iPhone 8 Plus, Samsung Galaxy Note 20 Ultra, Note 20, Note 10, and Note 9, Galaxy S20+, S20, S10, and S9, LG G7, G6, and G5, Nexus 6, and Nexus 5. It also holds 7-8 inch screen size tablets measuring up to 5 inches wide, including the Samsung Galaxy Tab 4 7.0 and 8.0, Galaxy Tab 3 7.0 and 8.0, Galaxy Tab A 8.0, Galaxy Tab E 8.0, Galaxy Tab S 8.4, and Nexus 7. This mount is not recommended for phones or other devices without a case measuring 2.64 inches wide or less, including iPhone 8 or iPhone 7. The phone holder’s solid construction provides strength and reliability by featuring a spring-loaded mechanism that expands to securely grip large phones and midsize tablets. Arkon recommends using the RoadVise XL Holder with smartphones with skins and ruggedized cases. The low-profile phone holder keeps rear smartphone cameras free for spontaneous pictures or videos. The 4-Hole AMPS drill base pattern consists of four holes in a rectangular pattern spaced at 30.17mm x 38.05mm (the center-to-center distance between holes). This tough, low-vibration pedestal measures approximately 4.5 inches high from the bottom of the base to the top of the pedestal (not including holder), and is made of a combination of plastic and nylon. The pedestal’s double ball adjustment provides 360-degree rotation and the ultimate flexibility in positioning the device at any angle. The mount can also be screwed directly into your vehicle’s console. (Warning: Drilling into the vehicle may cause damage. Use caution and consult a mobile install professional to avoid drilling into any sensitive vehicle components.) Garmin GPS devices can also be mounted by simply removing the holder and revealing the 17mm ball mount base.
