You guys all have excellent suggestions.
I'm probably going out to buy one this weekend... I've never used a GPS before so I'm new to using one. I've been reading here and there but let me know if I can do this with the 500/600 explorist:
- Load the map of Canada and USA in an extra SD card (wondering if they will all fit on a 1gig SD card.
- When driving will it automatically load the maps it needs on the SD card or do I have to do something once It needs another map that exists on the SD card?
I want as smooth of a trip as possible when driving as possible.
- When driving on the highway, I'm wondering if I have to add every gas station, restaurant, etc myself or if it will display this information?
