I am getting the Garmin edge 800 this year for Christmas, and I had a question about it. I have heard that the base maps, are ok, but that they are missing some of the real power and aesthetic of the purchasable sd cards for it. I decided that instead of going out and using 20000¥ on a sd card right of the bat, I would first try one of the online free maps, such as the openstreetmaps. But I was wondering whether the base version of the Garmin edge 800 comes with an sd card, or if I have to go out and buy one myself, and whether that is sufficient for it to work on my garmin edge 800. Also if you prefer one online map service over another then please tell me.
