Hello ddabcd277 and thanks for the information you provided. I am having a hard time finding a tutorial on how to do this from start to finish and concerned about trying to piece information together. When you say patch the FW, I assume you mean Firm Ware of the GPS?

For the Garmin Birds Eye subscription, at the end of the subscription if I dont renew would the information from original subscription still be usable in basecamp and the gps?
