WAAS Upgrades for GNS 430/530 Delayed

The purpose of this marketing memo is to update our dealers and customers on the progress of

WAAS upgrades for our GNS 430/530, GPS 400/500, and GNC 420 units.

The WAAS upgrade was regrettably delayed due to the necessity of a major change to some key

components, including a major software rewrite. Given the significance of these changes, the

availability of the upgrade is now projected to be the third quarter of 2006.

The complexity of this important project has increased as well as the R&D investment to design,

build, and certify our new WAAS-enabled GPS antenna, receiver, and associated software. In

spite of these challenges, Garmin is still committed to delivering WAAS capability to our

existing owners at a price of $1500, as previously promised.

Current owners must order the WAAS upgrade before November 15, 2005 to lock into the $1500

offer. Effective immediately, new purchases of GNS 430/530, GPS 400/500 and GNC 420s will

be upgradeable to WAAS, but at a to-be-determined price.

We sincerely apologize for this delay and ask for your patience and understanding. Garmin will

continue to communicate our progress to you and inform you of a firm delivery date as soon as

we are able.
