I didn't want to hijack the Garmin warning thread, but I have a question. I already own the City Navigator map software, which I got for my Garmin 60csx, and I'm assuming I can use it with an Edge 705. Does anyone know how to do this?

I remember having to register the maps so they could be used with the 60csx, so I'm guessing I can't just take the microSD card and use it in the 705 without doing something to it. I'd prefer not to have to buy another card, but I guess they're cheap enough that I will if I have to.

My recollection of the process to get the map software into the 60csx is that it was extremely frustrating, not very well documented, and unintuitive, and I'd hate to relive that. This is really the only thing keeping me from buying the 705 (despite all the warnings).
