A retention mechanism for a navigation tool of a mobile device includes a base member and a retainer member. The base member is adapted for insertion into a cutout of a support structure of the mobile device. The retainer member is configured for mating engagement with the base member. A navigation tool is retained between the base member and the retainer member, and a portion of the navigation tool extends through an aperture of the retainer member. A support structure of the mobile device can form a cutout corresponding to the base member to receive the retention mechanism. The base member can protrude through cutout so a bottom of the base member extends a distance beyond a bottom surface of the support structure, thereby allowing for the implementation of navigation tool on a mobile device without significantly altering the profile of the mobile device. |
