Actually its the Magellan Map 330. I bought one a couple weeks ago. Its nice. A little hard on batteries but not too bad. It comes with the power/data cable (I don't like that its a combines cable so I'm off in search of a second data cable to keep in the house), mapsend (for uploading maps into the memory) and a car mounting kit. Mine have for the most part been living in my car. One of these days I might actually get it hooked up to my ham radio. My only real complaint about it is a buzzing noise when you have the backlighting on. Other than that, its a great unit and Sam's Club has always been great about rebates.
I highly recommend this for any car setup. Its not bad for hiking either. Especially if you shell out the $100 or so for the topo version of mapsend.
