the rino 610 will not accept an sd card. also you cannot download a huntinggpsmaps card onto your computer, you can plug it in and run it on basecamp but it will not transfer. you would need to buy a download off of their website. the rino 610 only has 1.7 G of internal memory also so thats not a whole lot when it comes to maps once you have tracks, routs, waypoints, and spots marked. i would take it back and spring for a 650. far better unit IMO
