I got this to go with my recently purchased Nuvi 2589LMT. I have had other "bean bag" type mounts, but I really like this one, particularly because it does not attach with the suction cup arm, which I think is the weakness in GPS mounting in the first place (GPS occasionally falling off). The flexible base with grippy silicone bottom holds well and will work in any number of vehicles. I took 1 star off because although it holds very solidly, my Nuvi does vibrate a bit while driving which is a minor irritation.
Very nice case which protects my gps well, it does not fit the gps with the collar on, but that is no biggie, I just leave the collar attached to the mount, it is easy enough to re-attach the gps that way without removing the collar.
