I have the Garmin Nuvi 350 device and order this mount think it would work with my device base on the Amazon description of the product . the first time I order this I receive without the arm that attach to the GPS unit . I return it and have a replacement ship . the replacement come with the same problem ... only contain the bean bag base portion and again no arm . apparently , this be for some other unit because it do not work as it be ship . I will attempt to find this somewhere else . fool I once ... shame on you ! fool I twice ... shame on I !
