For those w/ SJ400, you can use (1) a suction mount (to be bought separately) to install in to the WINDSHIELD; clamp to install it underneath the REARVIEW MIRROR; or, the flat adhesive to install it on the DASHBOARD.

For me, it looks nicer if you will install it on the DASHBOARD using the flat adhesive.
