Thanks for your reply. Yah, I could go and buy another whole package from ebay or buy.com has the whole package for like $70.00. I still have the software, just need the BT-20 gps unit. Currently, I'm using the LT-40 usb unit with another laptop. Then again, Delorme is probably about ready to release the 2010 version and Fry's usually has them shortly after with rebate and such with some pretty good prices.
