After the problems I’ve had in the week I’ve so far owned my Edge 305 I hunted around and found who are the local (ie Australian) support.

Telephoned GME and they didn’t sound at all helpful, “Its a new device and we’ve only had them for a while, send it in and we’ll have a look at it.”

A few minutes later I found out that a newer release of the software is available, so I’ve updated it from version 2.30 to 2.40.
