Great solution for mounting a Garmin unit
Crutchfield Customer Review (What's this?)
Purchased to mount a 4.3" Garmin Nuvi in the dash bin above the radio on a Suzuki Equator. The bin has a series of small bumps on the bottom, but this did a nice job of sticking to the surface. Great elevation for the Garmin unit. Simple to install, no holes to drill, and can be removed (per directions) later if I change my mind on where it goes.
Pros: Easy install, no holes to drill
Cons: Not really a con, but make sure you know where you want to put it exactly before you stick it down, because it isn't moving again once it's stuck.
