Garmin Forerunner 405 Firmware Update

After a few false starts I was able to update the fireware on my Garmin Forerunner 405 on my MacBook Pro. Since the process was a little difficult to navigate, or more specifically, since it was difficult finding the starting point, I decided to write up my steps in a list.

The latest version of the firmware is 2.3 and boasts changes such as updated translations, increased log accuracy, navigation upgrades, bezel accuracy, and numerous other enhancements.

how long will it say LOADER LOADING?

I had mine also get stuck

I had mine also get stuck once on LOADER LOADING. I rebooted the watch (hold down both buttons) and started the process over.

I have had the Garmin

I have had the Garmin Forerunner 405 for over a year.
I am very happy with The Forerunner, at least since the first updates, the web site interface is great.
The battery in the heart rate monitor lasted about 12 months.
Recently I hit the 1,000 lap limit to the internal Garmin Forerunner 405 database, thats right one thousand miles!
The Forerunner does remove the oldest laps automatically for you.

Thanks for the post,
Beatnik ✌
