How do you feel the elevation does? Mine has been all over the map. I used it in Death Vally and it was to the exact foot of the pass I climbed, but in dense foliage it loses reception.
I got the Garmin software to up load local maps and plot routes on the computer. I like the PC version a lot and they have updates available on the Garmin site so the interface (for the PC) has been improving over the years. I have all the local street info uploaded to my Garmin for Baltimore, Annapolis, DC, Cumberland, York and areas in between.
If you want to get together sometime I might be able to help you figure out or work around some obstacles.
The elevation displayed is a combination of satellites and barometric pressure (for fine adjustment,) the satellite calculation is best when it locks on more satellites especially on the horizon so recessed areas can be off and barometric pressure can change over time trowing off the reading till more satellites are acquired. It bugs me when I ride down to the Inner Harbor and it shows my elevation at -14 feet but that really is a small error and does not really effect my enjoyment of the unit. On rare occasions I will get an outrageous elevation reading but it seems to self correct and not influence my overall elevation gain for a ride.
