Interesting you've had two fail and redthunder has had his fail too however I notice on yours the connector appears to be plastic where on ours it is a metal ring? Perhaps this is an improvement garmin have made in response to the issue? We are currently thinking go for blue. Can always add a second hanger on the orange for times when there is a codriver or the white locker is being used? But we will learn from using it if that is going to be an issue I'm sure.
When I sent it back to Garmin for repair. The replacement came back with a metal ring. So maybe that will stronger. Great radio otherwise.
