Shareholder Rights Plan [Abstract]
Shareholder Rights Plan	12. Shareholder Rights Plan On October 24, 2001, Garmin’s Board of Directors adopted a shareholder rights plan (the “Rights Plan”). Pursuant to the Rights Plan, the Board declared a dividend of one preferred share purchase right on each outstanding common share of Garmin to shareholders of record as of November 1, 2001. The rights trade together with Garmin’s common shares. The rights generally will become exercisable if a person or group acquires or announces an intention to acquire 15% or more of Garmin’s outstanding common shares. Each right (other than those held by the new 15% shareholder) will then be exercisable to purchase preferred shares of Garmin (or in certain instances other securities of Garmin) having at that time a market value equal to two times the then current exercise price. Garmin’s Board of Directors may redeem the rights at $0.001 per right at any time before the rights become exercisable. The rights expire on October 31, 2011.
