Question: Do I also need a Scan Dish card to operate this product?
Document: The GPS is very accurate I thought it would be useful hiking, but as it turns out I take this on travel with me because it is ruggized and smaller then my TomTom. I also like the fact that I can use AA. the more expensive models have built in camera, but I didn't see the need. I would recommend this product.
I have owned and killed three gps units. This particular unit is by far the easiest unit of the three to operate. The touch screen was relatively visible in sunlight and the battery life was better than expected. So far, this unit has survived three kayak trips through the Everglades that included the unit being completely submerged in salt water. I am quite satisfied with the product, its price, and the fast shipping provided by the vendor.
The lack of detailed written instruction makes it impossible to learn how to operate in the field. Printing your own from the the DVD provided is not a good option. When a company goes cheap it makes me wonder if the product is the same.
I just don't like it. I want the buttons and joystick back. Touchscreens and gloved hands don't go together. You need two hands to operate it. The menu system is for the birds. It is extremly hard to read in the sun. I have really used this unit. I would not buy it again.
I've used Garmin for a long time both in aviation and handheld GPS...Garmin truly makes the best navigational products out there. I bought the Oregon based on the ease of Geocaching and the extra menu that links and saves all info to that geocache. I love it and it makes it that much more fun. However, I have also used it hiking around several mountains, trails, and dead reckoning. It's real user friendly and honestly doesnt even really take a manual to learn to operate.
The only reason I gave this four stars is because this is my first GPS. My Brother in Law had one that he had to toggle to use the functions, but I prefer the touch screen. You can use regular batteries, but they do drain more quickly because I'm such a novice and am not quite use to it yet so I leave it on longer. I would suggest to get the streets/maps card with it because it'll make things alot more easier. Great product!
This GPS is easy to use, fairly intuititve, works well with other software I've downloaded from the Internet. Screen is very nice, batteries (lithium rechargables) last a good long time. I did get a SD card to put in it, although I really didn't need it and don't find it to be that useful.
If pictures are very important to you bring another camera along. I really liked the clip-on option that came with it. The compass was perfect. You do need to get the map card of you area. The preloaded maps are not micro enough, so put that in your budget. I think it is the best small handheld out there. Happy hiking!!!! !
You can get both the 24k map and city navigator on the same SD card, just look it up. It's beneficial in that you can have multiple maps active at the same time. There are other maps that the Garmin GPS's support that are free, you just need to look them up. Same goes for international maps. I will be taking mine to Puerto Rico and expect street maps and car navigation to work(no voice).
The car kit doesn't charge the unit though, so keep that in mind and remember that you are still going to need to replace the batteries pretty religiously.I'm glad I didn't buy the Garmin carrying strap with Carabiner, because it comes with one in the box. I bought the extra 24K Topo Maps and had a little trouble getting the mini-SD card to seat properly.
Answer: I'm afraid I don't know what that is. But I haven't purchased any extra products for this devise and it works great.
