Firmware Versions

You update it through the use of Garmin Express. You need to register the unit with GE as you would a head unit.

Improves from new Varia version (2.20)

Hello,

I've already posted this on dcrainmaker site:
after first ride with the new firmware I’m somewhat concerned.
Seems to me that while some false positives are gone some “false negatives” are introduced.
For example it won’t report a car that is going slowly behind you. Once it accelerates it will notice it.
I definitely felt more secure with the previous firmware version.

Does anyone know, whether it is possible to downgrade to previous version of firmware?

I did notice this myself yesterday. Rare but under certain conditions, I did not get a beep or dot indicating car behind. It was similar to what you described. This was with 2.00.

As to reverting back to older firmware, I don't know. When you plug in the unit to your PC, does it appear as a drive?

It does actually. But even if it could be used, there is nowhere to get the previous version of firmware I'm afraid.

Look at the bottom. The 2.00 and 2.20 versions of the Taillight firmware are present.

Great, thanks! Naming the file gupdate.gcd and copying it to the device did the trick.
