I have a gp v that I really like and this be one of the best add-on for it or any Garmin GPS .  the gp v come with the require mount bracket , and other model do too , but if not , you need to make sure you get it along with this .  this friction mount be relatively small but stay well on all dashboard I have use it on . it be pretty flat so it travel well in a suitcase or carry-on bag . it allow you to position the unit in the most appropriate spot in the vehicle and then use the clap attach to the GPS , adjust the angle of the display so it be optimal .  Detaching and re-attach the clamp unit with the friction mount could not be easier . for such a small and inexpensive add-on , I could not ask for more .
