I'm not sure the memory capacity on Garmin units is the only (and the main) limitation. What about the processing power? Loading a huge amount of map data onto a unit probably slows down its processing (map rendering, for example). I haven't tried uploading a large map on my Garmin, but I'm wondering if it affects the performance? Have you had any experience with it? And one more thing: how long would it take to upload a large map? Even for small maps (20 MB) it takes about minute or so.
