I have used this bracket plug assembly for two years and it works great, even in the rain with no issues.
I recently purchased a mount allowing me to use the Zumo 660 from my wifes RT so no longer need this one.
The Garmin is a 57lm, yes it a car version and will not bluetooth or plug in to the bike harness.
Thanks for looking and ride safe.
