Adding Maps to GPSr using Mapsource
I recently got a Vista HCx...pretty cool unit, and my first 'hiking' GPS. Previously, I owned a PDA with a bluetooth GPS receiver, and after my first foray into the GPS world, I was looking forward to having a dedicated unit that was waterproof and durable.
I was wondering if anyone has experience loading maps onto the Vista using Mapsource. I have City Navigator and Topo Canada, but it seems that every time I load new maps onto the unit, the existing maps on the unit get deleted. I.e. I loaded the City Nav maps for Vancouver onto the Vista; when I got Topo Canada, I loaded topo maps onto the Vista, and all the City Nav maps are deleted. This is confirmed because the "show/hide" options on the Vista no longer have "Show City Nav Maps" as an option any more.
I know I can have both City Nav and Topo Canada maps on my unit by loading BOTH at the same time from Mapsource. But I wanted to know if there was a way to add one or two maps to the Vista without having to reload EVERYTHING all over again as it's quite a long process to select and wait for the computer to do all the work.
Thanks in advance.
