I just purchased a Tiger 800XC. As such, my funds are somewhat limited at the moment, but I do want a GPS. I have the opportunity to buy either a used Garmin 2720 ($100) or 2730 ($150) locally, along with a cradle and power wires. My desire is to have a GPS to get me to addresses, and maybe follow pre-made gpx routes with it. Is that possible? Are the 2720/2730 good units, or should I pass? Would I be better served with another GPS? Thanks!
