G Firmware for iAero III

[fmullin]

I have an iAero III. I also have a Garmin 705. I have the latest firmware (4.02) for the iAero III. But I don't explicitely have the "G" firmware. Is that included, or do I need to get that?
Specifically, what do I need to do to get these two computers talking to each other!
Thanks,
Frank

I think all you will need is the G firmware, Fernando can probably back me up on this. He's the resident Garmin expert.

That's correct. You need the "G" firmware upgrade available here:

Fernando, since the IAero III and iAero III G both cost the same, why do I have to pay another $99 to get the firmware for my IAero III?

I believe it's because the iAero comes with the trainer option already installed and comes with speed and cadence sensors.

The "G" comes with the Garmin unlocked but you would have to buy the trainer option. The "G" isn't supplied with any sensors since you supposedly have the Garmin sensor.

You need to buy one or the other based on your needs.
