I bought a Magellan Meridian Gold three weeks ago because i couldn't wait for my husband to buy it for me for Christmas... when I heard about Geocaching, I had to start RIGHT AWAY!! He would like to buy me some accessories for Christmas since he couldn't get the GPSr. I know I'd like some street mapping software, but which one? Also, what else should I ask for? Dash mount? I bought it at Wal-Mart and they only seemed to have the unit, no extras, so I have no idea what could be available for this! I think he would be looking to spend around $150-$200. Thanks in advance for your suggestions!
