Garmin Chat Support:
We are working on a solution to ensure the quality of the BMW Motorrad Navigator VI. We are expecting a revised BMW Motorrad Navigator VI to be available in the second half of 2023. What I can do for you today is go ahead and exchange your Navigator VI for a replacement and add you to a list to be contacted once we have more information about the revised Navigator VI.
Also the replacements are on backorder till early/mid February.
