I've been using an old GPS V and it has done well, given its limitations. But now I have a problem - no complete software because of a new computer and I can't find but one of the 2 CDs to reload the maps and Garmin's program into the new computer. Solution? I checked around for the last few months and finally found a deal on a Zumo 660 at www.harboraudio.com for only $629.95. (Everywhere else seemd to be getting $799.99 for it.) Anthony there was really on the ball when I had problem ordering on line. He says they should get it to me about 22-23 April. GPS V for sale with fresh batteries, power cable, mount cradle and instructions, but only 1 N America CD. Make a reasonable offer over $25 and it's yours.
