I just purchased and received a 500 a couple of days ago. I had been using a 210 for some time and decided I should move into the real world and operate in glorious living color! And I am very please with it. Can't say enough good words about it but my only experience with a handheld is with Magellan. I put in a small SD card and works well. I use it with Mapsend DirectRoute as I did with the 210.
One point when using that configuration (Mapsend an Explorist) Mapsend will only communicate with one Explorist. So if you have 2 units or upgrade as I did, you need to get rid of the old serial number and get the new one in and configured with Mapsend. That took me quite some time...trying to communicate with the help desk and almost non-English speaking technicians!
But bottom line I am very pleased.
