My Hema Navigator HN7 crashed after doing a software and map update using Hema's NaviExtras software. I got in contact with Hema support and then posted it over to them. They received it on Wednesday this week. This is the response I got back from them today, just two days later...
This courtesy email informs you that your navigator has been repaired, updated, and ready for dispatch from Hema under warranty. The following works have been provided:

That is truly amazing service, and I've congratulated them on their truly excellent customer support. I will have my HN7 back in record time, updated and ready for our trip to FNQ and Mackay.
