I bought one of these units, it works great with Inflight (my GPS is COM2, 4800 baud).Only problem is it doesn't save my default settings (I am on the demo version) and this is the one thing that makes me wary of purchasing it, as the device was being set up for my slightly non-tech savvy partner who will be a little miffed she has to set the GPS device, orientation etc. up each time.
Have you had the same problems with settings not being saved?
I loaded up on the SD card and it worked fine.
