If your talking gamin topo Australia yes unlock codes were needed and for the DVD product one unlock code only was supplied and sounds like it has been consumed.
Hi Brian, that helps clarify my question then, I've got the Garmin topo maps for Australia, I'm the one who's consumed the unlock code, but does that mean that I can't view it through basecamp or install it on my device? Are there any step by step guides?
