Garmin Ltd.

Ladies and Gentlemen:

We have acted and are acting as Swiss counsel to Garmin Ltd., a stock corporation incorporated under the laws of Switzerland (the Company), in connection with the Registration Statement on Form S-8 (the Registration Statement) to be filed with the United States Securities and Exchange Commission (the SEC) on the date hereof under the Securities Act of 1933, as amended (the Act), with respect to the registration of an additional 2,000,000 registered shares of the Company, CHF 0.10 par value each (the Registered Shares), that may be delivered pursuant to the Amended and Restated Plan (as defined below). As such counsel, we have been requested to give our opinion as to certain legal matters under Swiss law.

Capitalized terms used herein shall have the meaning attributed to them in the Documents unless otherwise defined herein.

I. Basis of Opinion

This opinion is confined to and given on the basis of the laws of Switzerland in force at the date hereof as currently applied by the Swiss courts. In the absence of explicit statutory law, we base our opinion solely on our independent professional judgment. This opinion is also confined to the matters stated herein and is not to be read as extending, by implication or otherwise, to any document referred to in the Documents (other than listed below) or any other matter.

For purposes of this opinion, we have not conducted any due diligence or similar investigation as to factual circumstances which are or may be referred to in the Documents (as defined below), and we express no opinion as to the accuracy of representations and warranties of facts set out in the Documents or the factual background assumed therein.

For the purpose of giving this opinion, we have only reviewed originals or copies of the following documents (collectively the Documents):

(i) A copy of the resolution passed by the shareholders of the Company at the Company's annual general meeting held on June 7, 2019 (the Shareholder Resolution), as reflected in the minutes of such meeting, regarding the approval of an amendment and restatement of the Garmin Ltd. Employee Stock Purchase Plan (the Plan) that, among other things, increased the number of Registered Shares available for issuance under the Plan from 6,000,000 to 8,000,000 Registered Shares (the Plan so amended and restated the Amended and Restated Plan);

(ii) a copy of an extract from the minutes of a meeting of the Company's board of directors dated February 15, 2019 (the Board Resolution), including, among other things, a resolution approving the Amended and Restated Plan;

No documents have been reviewed by us in connection with this opinion other than those listed above. Accordingly, we shall limit our opinion to the Documents and their legal implications under Swiss law.

In this opinion, Swiss legal concepts are expressed in English terms and not in their original language. These concepts may not be identical to the concepts described by the same English terms as they exist under the laws of other jurisdictions.
