Summary: My main purpose of purchase in this Hand held GPS is back country trekking use. So, I choose Topo U.S 100K map(DVD-Rom) bundle version. (regular unit will not come with it) also get 1GB micro SD card for expandable memory. Overall; Durable with all weather, Accurate (9ft to 15ft pointing in most weather condition), super last long battery life (about 30 hour constant use, which almost two time last longer than any other hand held GPS in today's market) Geocache friendly...
Summary: I bought this unit as a Christmas 2007 present for my husband. He is trying to use it during his hikes in the Taos mountains. Unit freezes up every 15 minutes or less. Information lost. Updating the software had no effect on the problem. The internet is replete with descriptions of similar problems with this unit and there are no patches for it; unit must be replaced. I am very disappointed.
Summary: eTrex has been a disappointment. I own 2 Garmin Nuvi 350s and love them. I ordered eTrex Vista HCx for my mountain bike. It would not allow me to unlock the "City Select North America v7" map (that comes with Nuvi). Their tech support told me to return the unit (at my cost!), and they would send me a refurbished unit. The refurbished unit would not operate on battery power. It was fine when plugged into my laptop via the USB port.
Summary: I was very dissapointed. After reading other reviews and the specs Ii was expecting an accurate GPS device. I found it to be off by 150-250 ft at a minimum. When I was out an about in the mountains, and was close to a waypoint in a canyon, it shifted direction constantly. I have already returned this device and will be looking for something better.
Summary: I had 2 of these from new, returning the first for the second. Both of them exhibited the same fault - namely they hang / freeze during use. They hang at random points, any time from switch-on to several hours later, so very unpredicatble and very unreliable. They hung / froze regardless of battery type, or whether the Micro SD card was plugged or not. I updated the software in each of them to the latest - v2.6. No difference.
Summary: Warum nur 1 Stern? Weil ich seit 5 Stunden wie ein blöder versuche gekaufte Karten auf dem Gerät zu installieren. Die mitgelieferte Software "MapSource" wird nach dem Installieren automatisch nach Einwilligung aktualisiert. Ich musste jetzt in verschiedenen Foren (!) erfahren, dass die Garmin hier ganz großen Mist verbockt hat: MapSource wird anschließend unbrauchbar, verschiedenen Module fehlen. Es ist unmöglich Karte auf das Gerät zu spielen.
