The dual GPS\/GLONASS capability is particularly beneficial in high-latitude cruising areas — such as the BC coast, Alaska, and the Pacific Northwest — where GLONASS satellite geometry can significantly improve fix reliability. Confirm connector type and cable length requirements, and verify compatibility with your specific Garmin device before ordering.\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43943847755812,"sku":"GAR-010-12017-00","price":132.96,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_6e620b21-4b6f-41a5-96e5-cbb4be0e9d7b.jpg?v=1784065760","url":"https:\/\/marisolmarine.com\/products\/garmin-ga-38-gps-glonass-antenna","provider":"Marisol Marine Company","version":"1.0","type":"link"}
